90 kW bidirectional Power Module with 3-channel DC output that can be used in various configurations. Suited for bidirectional energy flow between the supply grid and DC loads and sources.


The figure below outlines the conceptual power schematic. The power module contains all necessary voltage, current and temperature measurements, configuration and connection contactors and safety features such as emergency stop, protection against overcurrent, overvoltage and overtemperature, fuses, covers on high-voltage parts and a door sensor.

Configurable filter

As outlined below, each PMx leg has a reconfigurable filter that can be adjusted according to the connected load/source.

V1 DC Bus voltage measurement
I1 Inverter current measurement
L1 Primary inductor
C1 Primary capacitor
V2 Primary capacitor voltage measurement
L2 Secondary inductor (bypassable)
I1 Output current measurement
S Output contactor
R Precharge

Typical uses for LCL: current injection/rejection into stable voltage source (grid, ...)

Typical uses for LC: high dynamic voltage source generation

Typical uses for LCLC: xxx

Typical uses for LCC: xxx

Important note: Although the reconfigurable filter enables a wide variety of devices to be connected, Triphase cannot guarantee correct operation of its standard software components for all possible external converter interfaces. When connecting an external switched-mode converter to a Triphase current- or voltage-source interface, care must be taken to properly handle potential resonances between the external converter and the Triphase converter. Adaptation of the software or adaptation of the filter components may be required.

Monitoring, measurements and safety

The measurements indicated in the schematic above are electrically isolated and are captured at control model speed (typically 8-16 kHz). The measurements are available in Matlab/Simulink (through the SDK) where they can be used for further processing, analysis and can be logged on the RTT. Automatic, configurable overcurrent- and overvoltage-protection is available with µ-second reaction times (3-5 µs) for disabling the solid state switches and for disconnecting the input/output contactors.


Housing and connections

Each PMx module is built into a Rittal TS8 enclosure. Terminal for the connections are made inside the cabinet for safety reasons.
