چکیده
This paper presents the operational modes and the design of the active clamp flyback inverter. The auxiliary switch, clamp capacitor (Cclamp) and resonant inductor (Lr) are used in flyback inverter to minimize the spike voltage at the transformer primary side. Therefore, the voltage stress of main switch can be decreased. The active clamp circuit can also help the main switch in order to achieve ZVS conditions by using the resonant capacitor (Cr1) parallelled with the main switch and resonant inductor (Lr). The simulation and experimental results are compared. The 800-W prototype circuit is provided to verify the system performance. Keywords—Flyback inverter, active clamp, zero voltage switching condition.

Highly efficient flyback microinverter for grid-connected rooftop PV system
This paper proposes a high efficiency DC-DC flyback converter with a resonant full-bridge inverter to use in PV systems. The flyback converter is composed of a resonant active-clamp circuit that limits the voltage stress and provides zero voltage switching (ZVS) turn-on and turn-off of the power switches. Therefore, the switching losses of the high frequency primary switches are negligible. A r...

The inverters are commonly used for medium power induction heating applications. In the process of induction cooking, a disc of metal is surrounded by a copper coil through which an alternating current is made to flow. The disc has a finite diameter and thickness. It is placed at a given distance from the coil and concentric to it. Secondary current is induced in the disc and this induced curre...
