ASYMMETRICAL VOLTAGE
CANCELLATION (AVC):
Asymmetrical Voltage Cancellation is a
generalized control technique for resonant
inverters
This technique is mostly applied to series
resonant inverters
This technique improves performance and
achieves better efficiency than conventional
fixed frequency control strategies
It considers ZERO VOLTAGE SWITCHING
operation , output power and load variations

ZERO VOLTAGE
SWITCHING(ZVS):
Zero voltage switching can be defined
as conventional square wave power
conversion
during the switch’s on-time with “resonant”
switching transitions.
