Programmable DC Power Supply
CINERGIA’s Programmable DC Power Supplies are power
electronics equipment designed to generate a DC constant voltage,
current or power. Thanks to its bidirectional hardware the DCPS
can source or sink the test energy while the grid-tied converter will
actively regenerate the energy back to the electrical grid
consuming a sinusoidal current with unity power factor and low
harmonic distortion.
FUNCTIONAL DESCRIPTION
KEY FEATURES
Operation modes:
-Constant Voltage (CV)
-Constant Current (CC)
-Constant Power (CP)
-Automatic test from Excel file
6.75 – 160 kW
It provides three DC channels:
-The three channels can be controlled independently,
allowing different voltage, current or power setpoints
-The three channels can be controlled in parallel, sharing
the same setpoint and providing 3 times the current
-In Unipolar 2Q applications, the loads will be connected
between one channels and the common negative.
-In Bipolar 4Q applications, the loads will be connected
between two channels

BACK-TO-BACK TOPOLOGY
The converter is formed by a grid-side Active Rectifier and an output DCDC converter sharing a DC-link. The
Active Rectifier allows sinusoidal current consumption with low harmonic distortion and unity power factor.
The DCDC converter generates three independent DC voltages controlling the voltage, current or power.

AC Input is connected to the grid (neutral connection is required). Galvanic isolation is recommended.
AC Output is connected to the Equipment Under Test (EUT) and can be used as:
- Three independent 2Q channels
- One 2Q channel (3 times rated current)
- One 4Q bipolar channel (connecting the load between two channels)
