Bidirectional power supplies send 93% of absorbed power back to the grid

By

Chroma Systems Solutions, Inc. announces the first phase release of its new 62000D bidirectional DC power supplies. Bidirectional DC power supplies offer two-quadrant operation with positive current/positive voltage as well as negative current/positive voltage, enabling both DC power output and regenerative DC loading. The absorbed energy feeds back to the grid with a conversion efficiency […]

Programmable dc electronic loads include e 300% peak-overpower capability

By

The 63200A series high power DC electronic loads are designed for testing a wide range of power conversion products including ac/dc and server power supplies, dc/dc converters, EV batteries, automotive charging stations, and other power electronics components. These units can be synchronously paralleled up to 240 kW and dynamically synchronized for generating complex multi-channel transient […]

Testing PV inverters

By

A photovoltaic, or PV, inverter converts the dc output of a solar cell or array into ac that can feed directly into the electrical grid (Grid Tie) or be used by a local electrical grid (Off-Grid). Solar PV inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking (MPPT) and […]

Batteries, battery analyzers and battery testers

By

The Leyden jar, invented by the Dutch physicist Pieter van Musschenbroek in 1746, preceded what we today call the battery. Originally, “battery” denoted several units connected in series or parallel. Thus, there could be a battery of Leyden jars. Actually, the Leyden jar works on a principle completely different from that of a battery. It […]
