Bidirectional DC Power Supply Upgrades Suit EV Component and PV Inverter Testing

Chroma 62000D bidirectional DC power supplies receive an upgrade to their operating range benefitting EV Component and PV Inverter testing.

Foothill Ranch, CA: Chroma, a world leader in automated test, is excited to announce significant enhancements to several models within their 62000D series of bidirectional DC power supplies. They have increased the operating current from 40A to 55A, a remarkable 37% improvement. This upgrade, along with a corresponding boost in output power, enables users to operate within a broader range, meeting their testing requirements more effectively.

In the electric vehicle (EV) sector, our upgraded models now support charging current testing needs for 11kW bidirectional onboard charger (BOBC) systems, accommodating both 400V and 800V high-voltage platforms. Additionally, in the renewable energy sector, our products are now compatible with commercial PV string inverters, featuring a 120%-150% DC input oversizing design to handle maximum short-circuit currents (Isc) of up to 52.5A.

How to Use RF Impedance Measurements to Ensure the Quality of Miniaturized Power Inductors

Most high-frequency and miniaturized power inductors are metal molding-type inductors. The magnetic metal powder surfaces are usually treated with an oxide layer to reduce eddy current losses at high frequencies, enhancing the usable frequency range and reducing losses and temperature rising. However, users typically cannot determine the particle size of the magnetic material and the integrity of the oxide layer after molding and sintering through visual inspection alone.
