逆变电源设计
- 电路分为两部分,笫一部分为DC/DC转换电路,芯片采用SG3525集成电路,作为前级MOS管的PWM控制输出,直流输出采用负反馈控制,来保证直流110V输出电压的稳定。 笫二部分为DC/AC转换电路,电路采用单片机控制,采用的微处理器型号为EM78P156,由其I/O口输出一对相位相反的控制脉冲信号(频率为50Hz/60Hz),在输出为正半周的时间内,输出信号以SPWM信号驱动的方式提供给逆变器中的功率开关管,控制输出功率开关管的导通与截止,从而输出幅值为110V的正弦波电压。

- DC power is steady and continuous, with an electrical charge that flows in only one direction. When the output of DC power is represented on a graph, the result would be a straight line. AC power, on the other hand, flows back and forth in alternatin

- Most electronic devices require AC power to work correctly because they are designed to be plugged into a standard wall outlet, which supplies AC power. These devices need a specific amount of low, regulated voltage in order to operate. AC power is e

- Power conditioners for low-voltage DC sources in Distributed Generation usually have two major functions: to boost the energy source output voltage and to convert it into an AC voltage. The voltage boost is usually done by a DC-DC converter.
