چکیده
This paper presents a high efficiency asymmetrical pulse width modulated dc-dc converter for photovoltaic application. The proposed dc-dc converter reduces the switching losses and current loss by zero voltage switching techniques. Moreover, the resonant circuit composed of the leakage inductance of the transformer and the blocking capacitor provides the zero-current switching (ZCS) turn-off for the output diode without the help of any auxiliary circuits. Finally,the reverse recovery problem of the diode is eliminated. The proposed paper is most suitable for variable input voltage (40-80V) application like PV. The results are verified with Matlab/Simulink and experimental results.
