The Design of a 150V/50Hz High-Quality Single-Phase Inverter Based on TMS320LF2407A

摘要

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.
