Transient Voltage Intelligent Regulation Device
A Dynamic Voltage Restorer (DVR) is an advanced power‑electronics device. It leverages cutting‑edge power‑electronics semiconductor and control technologies, combining them to ensure reliable power supply for end users. By employing state‑of‑the‑art DSP, FPGA, CPLD, and other control chips, the DVR continuously monitors grid voltage quality in real time. When a voltage sag or surge is detected, the system instantly switches the load’s power supply to an inverter‑based source, thereby safeguarding sensitive equipment from any disruption. The DVR’s switching and shutdown functions are software‑controlled, with a typical response time of less than 1 millisecond, ensuring uninterrupted power delivery.

The APFGD/SVGGD device is a novel power electronic system designed to address power quality issues. By connecting an external current transformer (CT) to continuously monitor the load current in the grid, and leveraging DSP, FPGA, and CPLD chips along with state-of-the-art fast harmonic or reactive‑power extraction techniques, it rapidly analyzes the harmonic and reactive components of the load current. Based on user‑defined setpoints, the system generates PWM pulses that drive a bidirectional converter composed of three‑level IGBT modules, thereby producing compensation currents that meet grid requirements. This enables dynamic, precise compensation of harmonic and reactive currents, ultimately enhancing power supply quality.
