High Efficiency
Achieves an efficiency of ≥98%, minimising energy loss during voltage regulation​.
HOW IT WORKS
The DSP control system continuously monitors the output voltage in real time via the voltage transformer. A 12-bit high-speed ADC, using frequency-multiplied phase-locked technology, samples 128 points per cycle to accurately convert the true RMS value. This data is then sent to the MCU control center. Based on preset parameters, the MCU regulates the servo motor, which adjusts the transformer brush system through a transmission device. By controlling the compensation voltage of the transformer, the system ensures stable output voltage.
