1.2 Required Equipment

  • Power supply able to support 48V, 12A, and 600W, such as HP 6030A
  • Electronic load able to support 35V, 14A, and 500W, such as Kikusui PLZ603WH
  • Function generator to apply a variable duty cycle PWM signal, such as Tektronix AFG3102
  • Oscilloscope such as Tektronix MDO34 with TPP0500B 10 × voltage probes and 30A TCP0030A current probes
  • 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 10A current shunts for efficiency measurements
  • A fan for cooling of the board if sustained high-current testing is desired
