What is a regenerative DC power supply (bidirectional power supply)?

A bidirectional power supply (regenerative DC power supply) is a power supply that functions as both a DC power supply and a DC electronic load in a single unit and regenerates power to the AC power source side during the electronic load operation. It is also known as a regenerative power supply, regenerative electronic load, or bidirectional power supply. The power supply is available in various applications, including evaluating inverters, DC-DC converters, motors, and other tests without switching connections.

Introducing the PBR series video Introducing the PBR series video | PBR series | Bidirectional (Regenerative) DC Power supply | Matsusada Precision

We recognize the importance of renewable energy for sustainable development, diversification of energy supply, and preservation of the environment, considering rapidly changing international situations. To address critical issues such as the energy crisis and climate change, carbon neutral and carbon offset initiatives to reduce greenhouse gas emissions are underway. The use of renewable energy sources such as solar power, wind power, and green hydrogen is also promoted. The development and spread of environmentally friendly technologies such as electrified electric vehicles with the power train system, household storage batteries, and fuel cells have been accelerated.
In response to the social conditions, the PBR series of regenerative DC power supplies regenerates power to use energy effectively, contributing to developing and evaluating inverters, converters, and other devices.

Applications

In accordance with the strategy, the development of innovative energy sources along with new battery research and development that do not emit CO2 is further accelerated. It will coincide with shift from vehicles having internal combustion engines to hybrid electric vehicles (HEV), plug-in hybrid vehicles (PHEV), Electric vehicles(EV), and fuel cell vehicles (FCV). And, motorcycles are also converted to EV bikes. That is, PBR/PBRM series, a regenerative power supply featuring its compact design and large capacity can provide highly powerful support for the development, evaluation, and shipment inspection.
