1 Introduction
High gain dc-dc converter topologies are derived for MEA (MoreElectric Aircraft), Micro and Nano satellite Electric Thrusters dur-ing last decades. Introduction of electric propulsion system needa dedicated dc-dc converter to convert the solar energy for elec-tric thruster [1-3]. Electric thruster requires a high DC voltage ofaround tens of kV depending on the type of electric thruster used[4]. Recent trend in power distribution in MEA is the use of highvoltage DC system. Certain values of system voltage under researchare 270, 350 and 540V [5]. Bidirectional DAB (Dual Active Bridge)dc-dc converter is introduced in [6] to meet the power demands ofaircraft electric loads. Boosting type converters are required boost-ing low level voltage from PV to the desired level of voltage. Usingconventional boost converter, voltage step up can be obtained byincreasing the duty cycle nearer to unity. By increasing the dutycycle the conduction loss, switching loss are increased which resultsin low efficiency [7][8].Series connection of multiple boost converterresults in high voltage gain. However, cost of the converter is in-creased due to too many components [9].By escalating the turnsratio of the transformer in isolated DC-DC converter, large volt-age conversion ratio can be obtained. However the diode stressvoltage and voltage spikes across the switches should be consideredwith certain remedial measures [10-13][30].Large voltage gain can beachieved with coupled inductor in the converters [14][16]. However,they suffer with similar disadvantages of isolated DC-DC convert-ers. By incorporating switched capacitor or switched inductor inthe converter the voltage conversion ratio can be increased. More-over, voltage regulation is poor [17].Based on 3SSC (three stateswitching cell) high voltage gain converter is introduced. However,the circuit weight and volume is high due to the presence of au-totransformer. Soft switching techniques are incorporated in highstep up topologies to improve its performance [31].

2 High voltage gain converters with volt-
age multiplier cell
The notable application of voltage multiplier cells are Travellingwave tube amplifier and capacitor charge transference [18][19]. Inboth the applications, it step ups the voltage to very high levelwithout the use of magnetic components. Incorporation of voltagemultiplier to DC-DC converter is not new and many articles werepublished in literature. High voltage gain converter is introducedwith capacitor voltage stacking cell [20]. However, the current stressresults in the circuit. Four switch high gain converter is introducedby employing cockroft- walton voltage multiplier cell [21].The con-ducting state of the switches are very complicated in that topology.The advantages of Voltage multiplier based step up converters arefollows:
• Diode-capacitor multiplier (VM cell) can be added to thetopology without modifying the original topology.
• No additional switch is needed apart from the main switch ofthe circuit which simplifies the gate drive circuit.
• Main switch, multiplier and output diode voltage stress de-pends on the number of multiplier cell. As a result of thisswitch with low on-state resistance can be used that mini-mize the losses and improves the converters efficiency.
Table 1 gives the comparison of different topology with voltagemultiplier. Several topologies are derived by integrating voltagemultiplier with voltage lift or coupled inductor or 3SSC or D-C-Lunit. It is found from the comparison that there is no promisingtopology which satisfies both voltage gain and voltage stress acrossthe switch with less number of components. The proposed converteroperating principle is given in section 3.Steady state (DC) analysisis made in section 4. Section 5 describes about the componentdesign and power losses of the converter. A comparative studyis made in the section 6. Section 7 presents the simulated andhardware results of the proposed converter.

4 Steady state performance analysis of
proposed converter
To simplify the analysis only stages 1 and 3 are considered for CCMoperation because the time durations of mode 4 and 6 are short.Mode 3, 5 and 7 are similar. At mode 1, the main switch SW is inON condition, the inductor L1 is charged by the input dc source Vg
, and the inductors in the switched inductor cells are charged bythe voltage across C1. The following equations are obtained fromfig 2(a)
VL1 = Vg (1)
VL2 = VC1 (2)
During mode 3, the main switch SW is turned OFF, the induc-tors L1 , L2 are discharged. The voltages across the inductor L1and LS1, LS2 can be
VL1 = Vg−VC1 (3)
VL2 = VC1−VCM1 (4)
During the mode 1 Capacitor CM2 is charged with the outputvoltage of quadratic boost converter with voltage multiplier cell.After mode 4, the load voltage is equal to two times of capacitorvoltage CM2 for one multiplier cell [M=1] similar to the converterin [19].
VO = 2VCM2.......M = 1 (5)

6 Comparison of proposed converter with
other high voltage gain converter
Two different comparisons were done in order to highlight the ad-vantage of the proposed converter. The Four converters taken forcomparison in terms of voltage gain and voltage stress are quadraticboost converter, Boost converter with voltage multiplier cell [7], Hy-brid POEL converter with self switched inductor cell and double selfswitched inductor cell [15]. The reason for selecting POEL Switchedinductor (SI) converter for comparison is the similarity in the num-ber of inductors and diodes in the proposed converter. Proposedconverter is the modified version of quadratic boost converter byvoltage multiplier (VM) cell. Thus quadratic boost converter andBoost converter with VM cell [7] are taken for comparison.

Table 4 Comparison of component utilization of proposed converterwith conventional converter
The comparison in Table 3 and Table 4 are performed withP=40W, V g =12V, V O =96V and f s = 60kHz and the results ofthe comparison are concluded as follows:
6.1 Static gain
Table 3 shows the comparison of proposed converter with Voltagelift converter [15], Quadratic boost and Boost converter with volt-age multiplier cell [7]. Fig 4 shows the graphical comparison ofvoltage gain between converters. One can see the proposed con-verter has high voltage gain compared to other converters taken forcomparison. It is found that voltage conversion ratio is about 22times that of the line voltage for the duty cycle 0.7.
6.2 Main switch and output diode voltage stress
From the table 3 comparative study on voltage stress on switch andoutput diode for proposed converter with other converters are made.Fig 5 presents the graphical comparison of switch voltage, multi-plier and output diode voltage stress of the proposed converter.The switch and output diode voltage stress depends on number ofmultiplier cell. By increasing the multiplier cell, the voltage stress

6.3 Switch/Diode utilization factor
Table 4 illustrates the comparison of switch and diode utilizationfactor of proposed converter with quadratic boost converter andboost converter with voltage multiplier cell [7]. Switch utilizationfactor is found to be high in the proposed converter. Due to in-crease in number of diode, total diode utilization factor slightlyless compared to boost converter with voltage multiplier cell. Totalenergy volume of inductor of the proposed converter is slightly highcompared to other converter.
7 Simulated and experimental results
The proposed converter is tested with 40W prototype to verify thetheoretical analysis. The electrical specifications are PO = 40W,Vg = 12V, VO = 96V, fS = 50kHz and RL = 230Ω. Inductor L1 ,L2 and Lr is chosen as 0.119mH, 0.239mH and 0.5uH respectively.Input and output capacitors are selected as 22uFas per equation 16.Voltage multiplier capacitor is selected as 0.5uf from the equation17. Fig 6 is the photograph of the converter implemented in thelaboratory. Simulation is carried out in nl5 simulator. Fig 7(a)-(d)shows the simulated waveform of the voltage across the multiplierdiode, output diode, multiplier capacitor voltage and inductor cur-rent. Fig 8(a) shows the main switch stress voltage is 47V for theoutput voltage of 95V. Fig 8(b) presents the voltage across the mul-tiplier diode which is equal to 49V for the output voltage of 95V.Fig 8(c) shows experimental output diode stress voltage of 49Vwhich is very less compared to quadratic boost converter where theswitch and output diode stress voltage is equal to output voltage.Fig 8(d) presents the multiplier capacitor voltage and is equal toVO / M + 1 . From Fig 8(a)-(c) one can see that the voltage stressacross switch and other diodes depend on the number of multipliercell and the expression to the maximum voltage stress on differentcomponents in the converter is given in table 2 which matches withthe experimental results.
