- Commodity name: AS.RG Elevator Energy Regeneration Device
The AS.RG series energy feedback device automatically detects the DC bus voltage of the inverter and converts the DC voltage from the inverter’s DC link into an AC voltage that is synchronized in frequency and phase with the grid voltage. After passing through a filtering stage, this AC voltage is fed back into the local power grid, supplying power to equipment located in the vicinity of the local grid, thereby achieving the purpose of feeding energy back into the grid.

Principle Introduction:
The AS.RG series energy feedback device automatically monitors the DC bus voltage of the inverter and converts the DC voltage from the inverter’s DC link into an AC voltage that is synchronized in both frequency and phase with the grid voltage. After passing through a filtering stage, this AC voltage is fed back into the local power grid, supplying power to equipment located in the vicinity of the grid. This process achieves the purpose of feeding energy back into the grid. The electrical energy fed back into the grid reaches over 96% of the generated power, effectively saving energy. Moreover, the device is equipped with a high-quality built-in filter and advanced control technology, ensuring that it does not interfere with the power grid or nearby electrical equipment.
Technological Advantages:
1) Utilizing a dedicated high-speed algorithm control chip, it promptly and accurately tracks grid voltage with minimal feedback overshoot and high efficiency.
2) It employs flexible feedback PWM pulse-width modulation technology, ensuring accurate phase output and effectively suppressing higher-order harmonics.
3) High-speed IGBT switching devices are selected, resulting in low switching losses and high operational efficiency.
4) Low harmonics. The power grid feedback exhibits low harmonic content, the grid-side current waveform is sinusoidal, and the total harmonic distortion (THD) of the current is significantly less than 5%.
5) High power factor. The power factor is approximately equal to 1, making it suitable for power compensation in the power grid.
6) No braking chopper required; a braking resistor can be optionally equipped to enhance the elevator system’s safety.
7) Uses a dedicated reactor for energy feedback, featuring high dv/dt surge resistance, low core loss, and long service life with high efficiency.
8) Safe and reliable protection functions, such as overcurrent, short circuit, temperature, and abnormal grid-side voltage;
9) It boasts advantages such as fast dynamic response, the ability to deliver high current in a short time, and high overall efficiency.
10) The entire unit employs a long-life ball-bearing fan for forced air cooling, ensuring low operating temperatures and high efficiency in power feedback.
11) Complies with multiple stringent national and industry standards.
