Working principle

HKK-SVG static var generator is a bridge converter composed of fully controlled power electronic devices for dynamic reactive compensation. The basic principle is that the load current is detected in real time by the external current transformer (CT), and the reactive content of load current is extracted by the internal DSP computing. Finally, the instruction value is calculated to control the PWM signal generator to send the control signal to the internal IGBT, so that the inverter can produce the reactive compensation current to meet the requirement, and finally realize the dynamic reactive compensation.
