How does SVG perform reactive power compensation?

1. Detect current: The load current is measured via an external current transformer (CT);

2. Reactive Power Calculation: The internal DSP analyzes the reactive power content of the load current through algorithms;

3.IGBT Control: The DSP generates PWM signals based on reactive power calculations to precisely control the switching sequence of the IGBT;

4. Generate compensating current: The IGBT switches at high frequency according to the PWM command, producing reactive current that matches grid requirements to achieve 

dynamic reactive power compensation.
