AN OPTIMAL HIGH STEP UP DC-DC CONVERTER FOR RENEWABLE ENERGY APPLICATIONS

electrical engineering

This paper presents an isolated resonant DC-DC Converter for renewable energy applications. In this method the voltage multiplier chain with dual coil provides output to the boost converter using a novel parallel input to take part in the input current and to reduce input current ripple in the two coils in parallel with the primary windings connected. On the other hand, it is proposed to change, and a series of interleaved output capacitors profit profitable high-voltage, low output voltage ripple, low pressure switch is connected with trying gets. In addition, the two sides increase connected to the secondary coil of the two primary currents parallel to increase the voltage balance between the productive diode and capacitor is coupled in series. In addition, activation key to the current zero level are being driven and connected inductors reasonable inductance leakage diodes to reduce the problem of reverse recovery. To analyze the performance of the proposed circuit it is designed using MATLAB Simulink software.
