High-power grid simulator saves energy as it tests EV, PV and Smart Grid components

07 September 2020

Researchers and manufacturers can test the performance of electric vehicle, photovoltaic and Smart Grid components using a new high power density grid simulator from MDL Technologies.

The four-quadrant, fully regenerative Chroma 61815 produces an AC power output of up to 15kVA in a form factor of just 3U.

The simulator is ideal for testing electric vehicle power supply equipment (EVSE), on-board chargers (OBC) and bidirectional on-board chargers (BOBC), as well as renewable energy equipment such as PV inverters, energy storage systems (ESS), power conditioning systems (PCS), microgrids and power hardware-in-the-loop (PHIL) systems.

Its regenerative operation means that power generated by the device under test can be fed back into the grid rather than dissipating as heat, which lowers operating costs as well as helping the environment. 

"With a rack height of only 3U, the Chroma 61815 offers the highest power density on the market," said MDL Managing Director, Mark Lucock.

Output can be single-phase or three-phase, and with voltage ranges of up to 350VLN and 606VLL the simulator can achieve 700VLN in a single-phase three-wire setup. If greater output power is needed, up to three units can be configured in parallel to produce 45kVA from a 9U form factor.

The 61815 can be used for testing to rigorous regulatory standards such as IEC 61000-3-2/-3-3/-3-11/-3-12 and IEC 62116, and for testing electric vehicle to grid (V2G), electric vehicle to load (V2L), electric vehicle to home (V2H) and energy storage system (ESS) systems.

Two other new models in the series are available, the Chroma 61809 and Chroma 61812, which offer the same high level of features but have lower power outputs of 9kVA and 12kVA respectively.
