Abstract :
This paper describes a converter where both series and parallel resonant circuits are used. In order to minimize losses switching is made at zero current (ZCS). The converter described consists of four transistors H-bridge connected and it is used in an application for an induction cooking stove with two hot zones. The switching frequency is 50 kHz. Different control strategies are discussed with the efficiency in focus
