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

A regenerative DC power supply (bidirectional power supply) is a power supply that has the functions of a DC power supply and a DC electronic load in one unit, and regenerates power to the AC power supply side (system) during load operation. Since it is equipped with functions of a DC power supply and a DC electronic load, it can be easily used to evaluate motor inverters, batteries, bidirectional DC-DC converters, etc. without switching connections.

In addition, the power is regenerated high-efficiently when the DC electronic load is applied, enabling significant size reduction, enabling the significant size reduction of the heat dissipation part.

Introducing the PBR series video

Main applications

It has wide application range such as in-vehicle inverters, converters, motors, and in-vehicle chargers (OBCs) for hybrid vehicles, electric vehicles (EVs), and electric motorcycles, as well as evaluation tests for V2H equipment and power conditioners for solar and wind power generation.

Since it has both power supply and electronic load functions, it can be used for charging and discharging tests of car batteries and household storage batteries without switching connections.

Furthermore, as it can simulate the charging and discharging of batteries, it is used as a battery replacement simulator (battery simulator function). Compared with conventional regenerative power supplies, Matsusada Precision's PBR/PBRM series featuring the compact body and parallel connection can respond with greater flexibility to diversifying application in evaluation and testing.

So, it is no surprise that the series is one of the most popular power supplies among many manufacturers in automobile, automotive equipment manufacturers, transportation equipment, robots, energy equipment, and battery-related field for development, evaluation, and production.

Bidirectional DC-DC converter evaluation

Using two PBRs, users do not have to worry about troublesome operations like wiring change and other setups which were the norm for conventional power supply and electronic load combinations. The power consumption can be reduced by using one unit in power running mode and the other unit in regeneration mode.

CV/CC Priority Setting Function

CV (constant voltage) priority/CC (constant current) priority mode can be selected and set. As is the case with diodes, a load tends to suddenly change the resistance at certain points. When the device is started in CV mode, the current will be momentary overshot. In PBR series, select the CC priority mode to suppress the occurrence of overshoot. The function can reduce the risk of damaging expensive loads such as high-power laser diodes.

Step transition conditions (transition time/transition condition/destination) can be output in CSV format.
CSV output format for operation log data
The operation log data (output voltage/current/power/battery charge rate/elapsed time, etc.) can be output in CSV format.
As you have only to pick up only the necessary information and edit it freely using spreadsheet software, etc., it contributes to reducing the time to create experiment reports, etc.
Link with temperature chamber (coming soon)
By linking with a temperature chamber, you can set the execution temperature for each step at the sequence execution. There is no need to configure at the temperature chamber side, which can save the setup time for heat cycle tests, etc.
