ABSTRACT

This work on the hybrid Inverter System using pulse width modulation is basically a Width Modulated (WM), Metal Oxide Semiconductor Field Effect Transistor (MOSFET) based Inverter which works on the principle of Pulse Width Modulation. The inverter uses the integrated (IC) and a pair of some MOSFETs to drive the load. The design and implementation starts with the power supply. Component selection was made with the aid of electronics data book, which made the design and calculations very easy. One main feature of this hybrid inverter is the monitoring section, and the battery-charging section connected to the inverter circuit. The inverter converts DC supply of the battery into AC power supply required by most electrical appliances/equipment when the AC main is not available and when the AC main is available. The AC main supply goes to the AC mains Sensor, the Relays and Battery charging section of the inverter.
