What is a regenerative DC power supply (bi-directional 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.

Features and benefits

More Space Saving for Better Workplace

Introducing the extremely compact PBR makes more effective use of your workspace. We have developed the smaller regeneration DC power supply for space saving aimed at installing other measuring tools, which makes effective use of the space at workplace.

How to compact

State-of-the-art semiconductor
In order to minimize the heat generation itself inside the power supply, we adopted the latest device including semiconductor elements of high efficiency via thorough examination. This enables the product to provide such a sufficient cooling function to maximize the high performance.
Air-through Circuit Blocking Technology
Following the structure review of the circuit blocking, the product has been made smaller, and we also have put more focus on the improvement of block arrangement contributing to excellent space efficiency by extremely reducing the dead space. Consequently, we achieved the significant development of the high-density mounting technology. So far, extra spaces inside the device had been required to release the heat. We successfully made the product even smaller to ensure the total amount of height of a mere 133 mm.


For all released soon. More lineups will be added at any time.

No need for always connected to a PC Sequence operation and operation log acquisition are available in places where a PC cannot be permanently installed!

You can create sequence data using not only the main unit but also a PC with the dedicated software.
Using the dedicated software, the created sequence data can be saved to an USB memory and loaded from the front USB port.

(1) Sequence function: MSS (Matsusada Sequence Software)

Easy to use for beginners

MSS allows you to create sequence data using the main unit or a PC with the dedicated software (MSS).
The software makes it easier and more convenient to create sequence data. The created sequence data can be saved to USB memory, and up to 1,024 steps of the sequence program can be loaded.

(2) Operation log display: MLV (Matsusada Log Viewer)

Instant graphing of operation logs

Operation log display function: MLV, the dedicated software can read and graph the operation log.
Logging to USB memory is available not only during the sequence operation as described in (1) above, but also during the local/external control.

(3) Battery simulator: MBS (Matsusada Battery Simulator)

Easy setting of battery operation with graphs

MBS can readily perform simulations of the I-V characteristic curve for the battery. And, the voltage/current can be set up to 1001 within the rated voltage/current values, enabling more liner more linear characteristic simulation.Patterns created by the Eedicated software can be saved in USB memory and loaded from the front USB port. You can perform intuitively by entering numerical values while looking at the graph, or directly dragging the graph to make settings.

Sequence Function

The sequence function allows programming of parameters such as step time, step amplitude, ramp, CV/CC mode, sequence end setting, step jump, and jump count by simply operating on the front panel. This option enables to generate optional waveforms, and you can use a great variety of applications including testing evaluation, and verification.

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.

Internal Resistance Variation Function (in CV mode)

Set the internal resistance to any value to generate a voltage drop when the load current flows.
Batteries, photovoltaic cells, and fuel cells can be simulated.
(The setting range of the internal resistance value is from 0 Ω to the rated voltage/rated current.)

Two-mode Lock Function

The lock function is available with the two modes: "Full" to lock all front panel operations, and "Normal" to lock all operations except the ON/OFF switch.
