Abstract :
A good design of the resonant elements is important in order to reduce the peak voltage stress and the peak current stress on the devices. The resonant elements also produce losses during resonant operation. So the stored energy in these resonant elements for the resonant operation should be optimum. In the selected resonant circuit, the trip currents decide the stored energy. Therefore by optimally controlling the trip currents, the efficiency of a soft switching inverter can be further improved. A simple method to calculate the minimum trip currents and the design formulas are offered in this paper. The experimental results verify the proposed design and the calculated minimum trip currents.
