Multi-functional High Quality Single Phase PWM Controlled Power Supply.

According to the requirement of a missile’s power supply, a 150V/50Hz high-quality single-phase inverter has been developed, and the CPU is TMS320LF2407A, and the main circuit is full-bridge inverter intelligent power module (IPM), and SPWM control method has been used too. The stability and the accuracy of the output voltage of this power supply have been improved because of the use of the digital PID regulator. The results of experiments show that the power supply has the advantages of the simple-circuit, the high-quality output-waveform, the high-stability output-voltage and so on.

In this paper, a novel single-phase bridge inverter is presented which can generate a more number of voltage levels with reduced number of switches, gate driver circuits and diodes as compare to normal multilevel inverter. Another feature of this inverter is its ability to prodeuce the voltages from a single dc-link power supply which enables back-to-back operation of converter. The proposed inverter with more number of levels can improve power quality, lower switching losses and produce high quality voltage waveforms. Also, the proposed inverter can be operated at all load power factor.The research of the model is done by means of computer simulation with the software MATLAB/SIMULINK. This configuration has very low dv/dt and common-mode voltage variation. Also this inverter is help full for reactive power compensation.

Testing Field

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.
