Chroma 62000D programmable bidirectional
DC power supplies provide both power
source and load characteristics. These two
quadrant power supplies allow power from
the DUT to be converted back to the utility
grid and so are ideal for testing renewable
energy power systems such as PV, storage,
and EV inverters as well as a wide range of
bidirectional power conditioning system
(PCS) and may also be used as a battery
simulator. 62000D has applications in testing
power components in electric vehicles as
well as bidirectional on-board chargers
(BOBC), bidirectional DC converters, and
DC-AC motor drivers and can perform power
conversion tests of Li-ion batteries in both
charge and discharge directions.
To illustrate the 62000D unique capabilities,
traditional DC power supplies need protection
diodes to back EMF during motor testing
does not damage the source. However, the
62000D bidirectional DC power supplies can
drive the motor and also efficiently regenerate
EMF to the grid, thereby avoiding the need
for blocking diodes while saving space,
energy, and configuration. In addition, the
fast cross-quadrant bandwidth of the 62000D
provides a transient response time of less than
1.5ms (-90% to +90%).
62000D bidirectional DC supplies include 9
different models with industry-leading power
density at 18kW in 3U of vertical rack space.
Model range from 6kW to 18kW, output
current ratings up to ±540A, and voltage
ratings up to 1800VDC. The master/slave
feature allows for up to 10 models to be
paralleled easily and safely up to 180kW.
62000D series is equipped with 100
programmable user settings through the
unit's List Mode. The fast response time fills
many testing needs, including the LV123 and
LV148 standards required for new energy
vehicle components. When combined with the
Chroma Softpanel, the user can conduct the
complex tests with simple clicks of the mouse.
62000D family of power supplies can easily
be used in any region of the world due to
its wide input range of 200-480 Vac and an
active PFC low-current harmonic feed to grid,
reducing power consumption, power system
configuration, and ambient temperature
changes under high-power testing. Control
options include digital USB, LAN, CANbus,
GPIB as well as analog APG interfaces.

Chroma's 62000D has a bidirectional switch-mode power supply design that offers two-quadrant operation with positive current/positive
voltage as well as negative current/positive voltage, enabling both DC power supply output and regenerative DC load. The absorbed energy
feeds back to the grid with a conversion efficiency up to 93% and can operate in constant voltage, constant current, and constant power
modes. Compared to traditional power supply and load, the 62000D two-in-one bidirectional DC power supply saves space, reduces energy
loss and heat dissipation, and is easier to wire and configure.
Renewable energy sources such as PV, EV, fuel cell, and battery are the market trend as the replacement of traditional energy sources (coal,
oil, etc.). Yet, the subsequent rising need for electricity will actuate the faster commercialization of distributed energy storage in microgrids.
The bidirectional design of power conversion devices urges battery applications to achieve high efficiency, high voltage conversion, and high
power density direction, which prompts the need for battery simulation (bidirectional power supply) testing designs.
