In this paper, a PWM (Pulse width modulation) amplifier drive module in radar servo system has been designed. It’s the core of the drive and made up of rectifier filtering circuit and IPM. The rectifier filtering circuit produces the DC bus voltage by rectifying and filtering the single 220V50Hz AC current. The IPM receives the control signal from the control module and makes the DC bus voltage inverted into the three-phase AC voltage to drive the motor. At the same time, the protection design and software design has been given. This system has high accuracy, good quick response features and strong dynamic carrying interference capability. It has been the driving form which is used in widest in the high-precision servo control area.
