Two-in-one bidirectional DC power supply with regenerable electronic load

Designed with bidirectional topology power supply architecture, it provides two quadrants with positive voltage/positive current and positive voltage/negative current operating ranges. It can be used as DC power supply or as a DC load for loading operation, and it could feedback absorbed energy to the grid, the conversion efficiency can be up to 94.5%.

This two-in-one bidirectional DC power supply also has the function as an energy feedback load and can be operated in constant voltage, constant current, and constant power working modes. Compared with traditional power supplies and loads, it has the advantages of small size, low energy loss, low heat dissipation and comprehensive testing functions.

With the popularization of electric vehicles, OBC on-board chargers run towards V2G (Vehicle to Grid), V2L (Vehicle to Load) and V2H (Vehicle to Home) through two-way charging and discharging with the grid management. The bidirectional DC power supply also provides a pure electronic load mode, with constant voltage (CV) / constant current (CC) / constant power (CP) modes, which can be used to simulate the charging behavior of the battery during the development and testing of on-board chargers. Only one device can meet the charging and discharging test of the bidirectional charger, unlike the traditional method, which requires a DC power supply and an electronic load.

Electric vehicle and energy storage microgrid power conversion test application

The rise of new energy PV / EV / Fuel Cell / Battery has become a market trend to replace traditional energy sources (coal, oil, etc.). However, a large number of grid connection requirements for electric vehicle operation and energy storage batteries will promote distributed energy storage microgrids commercialization more rapidly, along with the power conversion device moving towards bidirectional design, high efficiency, high voltage conversion and high-power density, combined with the rapid development of battery application trends, thus prompting the demand for bidirectional DC power supply test equipment.

Battery simulator

The bidirectional DC power supply can be combined with battery simulation software to become a battery simulator, which can simulate the operation under different battery power (SOC) conditions or specific battery characteristics V-I curve for battery charging or discharging simulation testing of the DUT (power conversion device), it is suitable for product testing such as on-board chargers, energy storage devices or motor drives.

Motor and drive test

The bidirectional DC power supply can allow continuous and seamless conversion between the two quadrants of the source and the load without changing the output characteristics or causing damage. It is suitable for many bidirectional DC-DC / DC-AC battery charging and discharging tests requiring fast charge-discharge conversion time. For the transient response ability of the current direction change, it has a high-speed transient response time, and the output voltage can be stabilized within 2ms.

When testing the acceleration and braking behavior of the motor driver on road conditions, the conversion between the battery system and the power system will result in the supply and recharging of electric energy. The dual-quadrant high-speed transient response characteristics can simulate the battery, convert according to the actual motor power demand and supply a stable voltage, and allow the current recharging when braking.

Automotive electronic standard test

The power supply has a built-in waveform generator, which can be expanded to achieve standard waveforms such as ISO 16750-2, ISO 7637, LV123 and LV 148. With the host computer software, one-key operation output test can be realized.

Photovoltaic inverter test

With optional MPPT function, the bidirectional power supply can simulate photovoltaic array (solar cell I-V curve), used for photovoltaic inverter MPPT point tracking test and aging test.

The I-V curve can be automatically generated by setting the corresponding parameters, and support parallel expansion of the same model models.
