1.2 Required Equipment

  • VIN power supply 20V to 60V
  • Electronic load to step for efficiency graphs, and for dynamic load testing such as Kikusui PLZ334WL, at least 660W
  • Oscilloscope such as Tektronix MDO34 with TPP0500B 10 × voltage probes and 50A current probe
  • Digital multimeters such as Fluke 87iii or 87V
  • For bode plots: Vector Network Analyzer such as Bode 100 from OMICRON lab
  • Thermal camera such as FLIR E75
  • Keysight 34970 data acquisition, switch unit along with calibrated 50A and 25A current shunts for efficiency measurements
