摘要
针对传统相控整流方式中,电网注入大量谐波及无功功率,易造成电源污染的不利影响。采用全控型开关器件,并将PWM控制技术引入整流电路,通过滞环电流控制方式,在稳定直流电压输出的同时,使交流侧电源电流波形近似正弦波,实现电能的双向传输。结合电压型PWM整流电路的控制方法,以STM32F103RBT6微处理器为核心搭建实验电路,实现PWM整流电流正弦化并可四象限运行,实现电能双向传输。
In view of the traditional phase controlled rectifier, the power grid is injected into a large number of harmonics and reactive power, which can easily lead to the adverse effects of the power supply. The PWM control technology is used in the control circuit, and the hysteresis current control mode is used to stabilize the DC voltage output. With the control method of voltage type PWM rectifier circuit, the experimental circuit is built with STM32F103RBT6 microprocessor as the core, and the PWM rectifier current is sinusoidal and can run in four quadrant, Realization of electric energy bidirectional transmission.
