Yaskawa servo drives are used to control servo motors, which are similar to AC motors and are part of the servo system. The servo drive takes the digital signal processor as the control core, which can realize more complex control algorithms and realize digitalization, networking and intelligence. The present invention adopts a driving circuit designed with intelligent power module (IPM) as the core, the driving circuit is integrated inside the IPM, and is equipped with overvoltage, overcurrent, overheat, overvoltage protection circuit, and the main circuit also adds a soft-start circuit to reduce the impact of the start-up process on the driver. Firstly, the power supply drive unit rectifies the input three-phase electricity through the rectifier circuit to obtain the corresponding DC current. Rectify the three-phase or commercial power supply, and then drive the three-phase permanent magnet synchronous AC servo motor through the frequency conversion of the three-phase sinusoidal PWM voltage inverter. The entire process of a power transmission can be simply called the AC-DC-AC process. The main topology of AC-DC is a three-phase full-bridge rectifier circuit.
