Switched Mode Power Supply (24V Dc 4A) for PV Application

Introduction

Switched mode power supplies are preferred in photovoltaic applications because of their inherent high efficiency. These are required to stabilize the output voltage, of PV generators, which varies over a large value depending on the incident solar radiation. A parallel combination of five of these can give a stabilized 24V dc, 500W source which operates over an input voltage from 30V to 50V dc.

Special Features: Input dc voltage:30V - 50V. Output dc voltage:24V. Output dc current :more than 4A.Output ripple :less than 100mV peak to peak. Output is short circuit protected. Output is over-voltage protected. Input is over-voltage protected. Frequency of operation :10kHz. Maximum efficiency at 100W:more than 85%. Converts 30-50V dc non - isolated 24V dc, 4A dc supply.
