User InputsNotes: Model Outputs1. WARNING, entire circuit INCLUDING CONTROLS are at line potentials. Insulated controls and 100.0 47.0 22.0 10.0 4.7 2.2 1.0 potentiometers MUST be used. Given: All Values nF2. This circuit is conceptual only and has not been tested. User assumed all risks. Circuit should be powered with low voltage/low power until operational characteristics are determined. Vrms = 140 VAC3. Cx will increase current into resonator, however makes circuit tune critical and possibly more susceptible Vpk = 198 VAC to kickback. Vdoubled= 396 VAC

Ptank = 1250 W (allows headroom for kickback, EMI/RFI). Fo = 100000 Hz5. Lp and Cx must be chosen to limit surge impedance of tank. This can be calculated via equations:

(1) Itank = 19.83 A(1) I = 2*pi()*P / Vpk I = tank current

P = Desired input power (watts) (2) Ctank = 0.08 uFVpk = DC bus voltage (or AC nominal rms * sqrt(2) )

(3) Ltank = 31.77 uH(2) C = I / ( 2 * pi() * f * Vpk ) C = tank capacitance (F)

I = tank current (4) Zo = 19.96 ohmsf = Desired resonant frequency (hz)Vpk = DC bus voltage (or AC nominal rms * sqrt(2) )

(3) L = tank inductance (H)C = tank capacitance (F)f = Desired resonant frequency (hz)

(4) Zo = Tank surge impedance (ohms)L = tank inductance (H)C = tank capacitance (F)

Equations (1,2,3,4) are from Fairchild Semiconductor Application Note AN-9012

4. IR2153D maximum input rating is 600VDC. DO NOT exceed 500VDC power supply input to chip / IGBT's

L = 1 / ( 2 * pi() * f )2 * C

Zo = ( L / C )0.5
