Regenerative DC power supplies are ideal for developing batteries, power regenerative inverters, and bidirectional DC/DC converters. Regenerative DC power supplies, also known as bi-directional power supplies, can perform both alternating current (AC) to DC conversion (power, DC power supply) and DC to alternating current (AC) conversion (regenerative, electronic load) in a single unit. In order to use energy without waste, vehicles equipped with power regenerative inverters and bidirectional DC/DC converters, as well as hybrid power conditioners for solar power that can be connected to batteries, are becoming more widespread and have larger capacities. Matsusada Precision's PBH series of regenerative DC power supplies are ideal for development, evaluation, and inspection of these products. Energy is recovered and returned to the grid during regeneration of inverters and converters and during battery discharge, thereby reducing unnecessary heat generation and saving space. The PBH series offers even higher AC/DC and DC/AC conversion efficiency, and is even more compact and high-density.

What is a 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.

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 PBH series of regenerative DC power supplies regenerates power to use energy effectively, contributing to developing and evaluating inverters, converters, and other devices.

CV/CC Priority Setting Function

CV/CC Priority Setting Function | PBH series | Bidirectional (Regenerative) DC Power supply | Matsusada Precision

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 PBH 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)

CV mode | PBH series | Bidirectional (Regenerative) DC Power supply | Matsusada Precision

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.)

Preset Memory Function

The series comes with the preset memory function by which the preset values can be automatically saved at power off. Additionally, the storage of up to three respective setting values of the output voltage/current/power is available.

External Analog Remote Control

The external analog remote control of voltage/current/power is isolated from the output of the power supply as standard. When controlling/monitoring multiple power supplies, you can use the product more securely as the external analog input/output control has a chassis (ground) potential.

External output ON/OFF

The output can be turned ON/OFF by the external relay or TTL signal. The logic of the signal can be selected by 5 V input.

Remote sensing

It ensures the prevention of stability deterioration caused by the voltage drop (VO-VL) by the resistance (R) of the output wire and the contact resistance (up to 0.5 V).

<Example>
(1) 10 units in parallel of PBH80V1000A33.5kW → 80 V/10000 A/335 kW
(2) 10 units in parallel of PBH1500V65A33.5kW → 1500 V/650 A/335 kW

  • Expandable to a total of 10 master and slave units.
  • In master/slave connection, the values of output voltage/current for the whole unit are shown on the output voltage/current meter of the master. (However, eachslave unit does not display the individual output values on the output voltage/current meter.)
  • Master/Slave control cables are also available as options.

Two-mode Lock Function

“Two-mode Lock Function” to prevent wrong operation

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. With the “full” lock mode, all operations on the front panel are locked to prevent erroneous operations. Meanwhile, the “normal” lock mode can lock all operations except the ON/OFF switch in which the emergency stop is enabled. It is a useful function that ensures what you consider to be “safety”. This is a convenient function that ensures what customers consider to be "safety". In both “Full” and “Normal” modes, Emergency stop is enabled with the POWER ON/OFF switch.

Two-mode Lock Function | PBH series | Bidirectional (Regenerative) DC Power supply | Matsusada Precision
  • Normal lock
    Switches the touch panel, and encoder are locked other than ON/OFF. It is further effective to prevent the erroneous changes of output values during the local control and to facilitate emergency stops.

  • Full lock
    All switches including the touch panel and encoder are locked except LOCK release. It is further effective to prevent the erroneous stop during the remote control and to completely avoid erroneous operation.

“Password Function” a new protection using password along with “Two-mode Lock Function”

In this function, to cancel the two-mode lock function, input a 4-digit PIN code. (Enable/Disable is selectable.)

It is available even during the operation, so you do not need to stop the output when you change the same sequence according to your needs. In addition, the skip function allows you to end the current step and move to the next step by pressing the skip button on the software screen.

High precision data management linked to measurement devices

The high precision measurement is available with a multimeter instead of the PBH unit. By connecting a multimeter, measurement data (voltage, current, power (calculated from voltage and current), and temperature) can be imported into our software for batch management. Thanks to the features, the high-performance data management is provided without a troublesome operation of collating the data. It was impossible up until now since conventional charge/discharge software could not be linked to external measuring instruments.

Graph display of PBH operation log data

Using MLV, Matsusada’s operation log display software, the sequence log data appears in graph.

Step transition condition in CSV format

Step transition conditions (transition time/transition condition/destination) can be created 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.

CAN communication with BMC, BMS, and BMU

With CAN conversion adapter for PC, you can check commands from BMC, BMS, and BMU via CAN communication as well as use them as the transition condition.
