DESIGN AND CONSTRUCTION OF 1.5kv A HYBRIDE POWER MODULAR INVERTER TRAINER KIT

ABSRACT

The reliability of Power Company Electricity Service varies greatly due to many factors including the design of the power grid, protective features, power system maintenance practices and severe weather. This work is on the design and construction of a l .5KV A Pulse Width Modulated (PWM), Metal Oxide Semiconductor Field Effect Transistor (MOSFET) based Inverter, which works on the principle of Pulse Width Modulation. The inverter uses the IC SG3524 and a pair of six IRFP260N MOSFETs to drive the load. The project is divided into four modules of which the design and construction details of the following two modules are covered in chapter three of this write up i.e. Transformer and Driver module. The focus is on designing an inexpensive, versatile, noiseless, no weather (environmental) pollution and efficient inve11er that gives a 220V modified sine wave at the output. The project can as well be used to train students. Some problems were encountered during the construction of the project which are listed in chapter five of this write up such as burnt AC voltage meter, and the solution proffered.
