Power and Energy Efficiency

At SJ Electronics we understand evolving requirements and offer power test solutions for design validation, characterization, performance testing and certification.

Today’s efficient power converters demand less input power per watt of output, but they also demand more in terms of power supply measurements. You’ve come to the right place to learn about:

  • Ripple measurement and noise analysis
  • Power factor and harmonics measurements for IEC61000-3-2 pre-compliance
  • Testing to Level VI efficiency standards
  • Standby power testing to IEC62301 Ed.2
  • GaN and SiC FET and diode characterization
  • MOSFET switching loss and safe operating area analysis
  • In-circuit inductor and transformer loss measurements
