ac single-phase power

Based on the need to develop and test the products, a single phase DSPbasedprogrammable AC power supply is designed.

基于产品研发和测试的需要，本课题设计了一种单相可编程交流电源。

The system consists of the AC input stage, single phase PFC, main inverter, output low-pass filter, auxiliary power supply, and load current sharing circuit, etc.

整个电源由输入电路、功率因数校正器、主逆变器、输出滤波电路、辅助电源、均流电路等部分组成。

Derived the formula for computing quadratic harmonics of output current in the single phase unit power factor ac DC converter based on analysis of the circuit module of the equivalent current source.

在基于对等效电流源电路模型分析的基础上，推导出了单相单位功率因数变流器输出电流二次谐波的计算公式，将输出二次谐波电流正、反向交替注入交流输入侧来抵消电流中的谐波。
