A Modified Class D Resonance Inverter for Operating in Load Independent Condition

فاقد چكيده فارسي

This paper presents a new topology to reduce the largest limitation on resonant inverters due to the resonance frequency dependency to load change. Load power variation under different conditions causes the resonant circuits become inductive or capacitive and consequently current flowing through switches will be lagging or leading in which in both cases eliminates the soft switching properties of the resonant circuits. By proposing new structure zero-current switching (ZCS) will be fulfilled and the current of the switches becomes load independent. The proposed topology reduces fabrication costs and overall losses and also the size of the converter will be reduced. The modeling and analysis has been supported with detailed simulation to verify the proposed topology.
