Design of a High Power Programmable Intelligent Switch

Abstract:

Based on the need to develop and test the products, a single phase DSP­based programmable AC power supply is designed. The power supply is capable of providing a stable AC voltage with adjustable amplitude and frequency over a wide range. Moreover, it can generate various high quality and low frequency arbitrary waveforms. Because of the advantages above, it will have great value in practice and a promising future in testing field. The main circuit of the power supply is to use rectifier and filter to make 220V AC voltage become steady DC voltage firstly. Then the inverter and the LC LPF are employed to produce the AC voltage which is required in the test system. The key part of the inverter is phase shift full bridge.
