Figure1: Induction control system
Resonance converter:
Aim of the resonance converter design is making switching at no voltage and no current.
Sharing energy between capacity and inductance provides power adjusting. Maximum
power is transfered at resonance frequency. There are three types of converter: serial,
paralel and serial-paralel..
Half bridge serial resonance converter:
After high frequency square wave gives to coil, inductance of coil and capacitors between
rectified phase and null generates sinusoidal current because of resonance.
Figure 2:Half bridge serial resonance converter:
Single switch parallel resonance converter (Quasi Resonance):
Resonance capacitor and coil are paralel to each other in this method and only one switch is
used at this topology.
