Description：
By adopting a topological structure with bidirectional energy flow function, it has the ability of 100% energy feedback. It can not only provide energy to the tested equipment but also allow the energy to be fed back to the power grid through it. Using full digital DSP control and dual-loop design technology for voltage and current, it has high control accuracy and fast response speed. It can quickly feed back the energy to the power grid. Meanwhile, it is equipped with internal discharge resistors. Even in the case of faults during the testing of electric vehicle drivers, it can still consume the energy fed back by the load, avoiding causing faults in the DC source.

Application domain：The WGHPD-DC series DC power supply is mainly applied in the new energy vehicle industry. The electric vehicle driver, as the controller of the motor, is the most important component in the power system of electric vehicles. It must undergo a large number of rigorous performance tests before leaving the factory. This DC power supply, when combined with the test bench, can conduct standard tests and verifications on the motor controller.
Characteristics：
1. Support for multiple units of the same capacity to be connected in parallel.
2. It has multiple output modes including constant voltage, constant current, and constant power. The voltage and current can be programmed and set.
3. The dynamic response speed is fast. The quadrant switching time is ≤ 10ms, and the dynamic voltage stabilization time is ≤ 5ms.
4. It uses high-power IGBTs and large-capacity capacitors for the bus, which makes it highly resistant to shock.
5. An internal discharge resistor is equipped. When there is a fault or emergency stop, the resistor consumes the controller's energy.
6. It can promptly protect in cases of excessive energy feedback to avoid damage to both devices.
7. It adopts PWM rectification technology, with a power factor greater than 0.99 and an efficiency greater than 92%.
8. A multi-stage filtering circuit design ensures stable output.
9. The mature digital control technology and the complete hardware filtering circuit result in low ripple content of voltage and current.
10. It uses a large-screen LCD screen, which can display multiple data that need to be monitored, such as voltage, current, power, etc.
11. It has complete protection functions: over-power, over-current, over-voltage, short circuit, over-temperature, etc.
12. The RJ45 communication interface it carries makes remote operation and automation more convenient.
