Passive Component Testing
Besides testing capacitors, inductors and resistors individually, the passive component 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. The tests not only analyze the characteristics of these components but also optimize the entire application process including the inspection of auto manufacturing and incoming/outgoing material, quality verification and RD analysis in order to meet the low cost/high efficiency requirements.
Passive component wide-ranging application field in power electronic products :
- Switch mode power supply(SMPS) : adapter, charger
- LED power driver circuit
- Photovoltaic(PV) : PV module, PV inverter
- Electric vehicle(EV) : BEV, HEV, PHEV
Passive component test solution :
- Electrical characteristic measurement :
Inductance, capacitance, resistance, impedance, dissipation factor, quality factor, leakage current, insulation resistance.
- Reliability(load life) test :
Bias current test, power loss & core loss test, ripple current test, high frequency withstanding voltage test, high frequency withstanding current test, temperature rising test.
