Abstract

This research proposes an invention of the switching power supply designed for a thermoelectric dehumidifier. This switching power supply consists of many important part which are a soft-start circuit, rectifier, boost converter, full-bridge inverter, high frequency transformer and the output rectifier circuits. The switching power supply can produce two voltage levels; 12 and 24 volts. The microcontroller PIC16F886 integrated in the main control unit manages the operation of the boost converter circuit and full-bridge inverter circuit by generating the driving signal to the IGBT switch in both circuits for better output-voltage stability. This switching power supply can provide power rating of 94.85 watts in total and have 83.20 % efficiency with a power factor high as 0.95 lagging.
