Improved AC-AC Converter For Induction Heating Applications
Induction heating applications require high frequency currents which are obtained using resonant converters
viz., Series and Parallel resonant inverters. The resonance frequency in these converters will be tuned to a high value. In this
paper a single-switch parallel resonant converter for induction heating is simulated. It is compared with the existing inverter
topologies; half bridge and full bridge. The circuit consists of input LC-filter, bridge rectifier and one controlled power
switch. The switch operates in soft commutation mode and serves as a high frequency generator. Output power is controlled
via switching frequency.
