EV/PHEV Chargers

The power conversion section of the EV/PHEV is composed of several power electronic units, which include the EVSE (EV Supply Equipment), on-board charger, DC/DC converter, motor driver, etc. The Chroma ATS (Automatic Test System) addresses the specialized requirements involved in testing the power electronics during not only the development phase, but also the production phase.

Passive Component Testing

Besides testing capacitors, inductors and resistors individually, the passive components test devices are also able to measure assorted electronic components composed of them. Individual components include wound components and communication and power filters; Composites include switches, connectors, lead wires, conductive, dielectric material, magnetic material and semiconductor components.

Electrical Safety Systems

The major test items of the Electrical Safety devices include AC/DC/IR Hipot tests for electronic components, and Ground Bond and Leakage Current tests for appliances. In addition to confirming whether the products comply with the safety specifications such as UL, CE, TUV and etc., the main purpose of the test is to ensure human safety and product reliability.

Medical Safety Systems

The Chroma Sentinel series of medical safety testers provide more than enough current for functional run testing as well as earth, enclosure, patient and line leakage current tests meeting IEC60601-1 compliance requirements.

LED Power Driver Test Guide

Chroma has defined this test specification to further advance the quality and technical development of the LED driver based on its 26 years of specialized knowledge in the power testing field and the professional testing experiences of various manufacturers.

LED Driver Testing

LED’s are a current driven DC device and require a converter so they can be powered from an AC voltage. These Power supplies for LED lighting are most commonly referred to as LED Drivers. LED Drivers have different operating characteristics from the typical AC to DC, and DC to DC Power Supplies used for most electronic equipment. They are often a constant Current output rather than a Constant Voltage Output. Chroma has created the industries first Electronic Load with an LED operating mode for simulating LED loading: the Chroma 63110A load module, for our 6310A series.

LED Test Solutions

The industry’s first LED simulator for LED driver testing. The LED’s forward voltage and operating resistance can be set to further adjust the loading and ripple current to better simulate LED characteristics.

Passive Component Testing

Besides testing capacitors, inductors and resistors individually, the passive components test devices are also able to measure assorted electronic components composed of them. Individual components include wound components and communication and power filters; Composites include switches, connectors, lead wires, conductive, dielectric material, magnetic material and semiconductor components.
