Design of Driver Testing System

1. Introduction
The AC speed control system usually uses IGBT pulse width modulation drivers to control the execution motor to operate in four quadrants, thereby meeting the

high-precision and high real-time requirements of the control system. The driver is the core part of the AC speed regulation unit in the control system, and its quality and performance

directly affect the accuracy and performance of the entire control system. However, once the driver malfunctions during use, it will affect the normal operation of the

entire control system. Therefore, it is necessary to design and develop a comprehensive performance testing system for the driver to quickly troubleshoot and ensure the performance quality of the control system.

2. Working principle of the driver and technical characteristics of the testing system

Figure 1: Schematic diagram of the drive speed regulation system

Drive speed regulation can generally be divided into four parts: rectification, DC holding, inversion, and control. The current regulator compares and adjusts the actual current

value with the given value, while the speed regulator obtains the actual speed value through the speed measurement motor and rotor position detection, and adjusts the speed value.

Drivers belong to high-power precision devices, which may cause mutual interference with the outside world, affecting normal operation. The noise signals generated by other

devices on the same power supply may also enter the driver through radiation and power conduction, and the high-order harmonics and radio wave noise generated by the driver

can easily affect the power grid and surrounding equipment. Eliminating interference and ensuring the normal

operation of the equipment is a major feature and challenge of this system. The standard grounding method is adopted in the design, and filtering devices are connected at the

front and rear ends of the driver. Surge current limiting circuits are connected in series in the circuit to effectively avoid mutual interference and ensure accurate and reliable testing signals.
