The third chapter mainly introduces the hardware design of soft starter, including the main circuit, control circuit, drive circuit, and protect circuit and auxiliary switched power design.
第三章详细介绍了软起动控制器的硬件设计，包括主电路、控制电路、驱动保护回路和辅助开关电源电路的分析和设计。
The modular approach allows the soft-switching circuit to be designed as an add-on optional module to a standard inverter, which can convert a conventional inverter into a soft-switched inverter.
模块方法允许软开关电路被设计成标准逆变器的可选附加块，可以把传统的逆变器转变为软开关逆变器。
The present invention adopts a fully electrical soft switch to conduct and switch off, thereby, the service life is long, and the degaussing circuit has no sound when being switched off.
本发明方案采用全电子软开关接通和关断，所以使用寿命长，消磁电路在通断时没有声音。
