pr4fa11elk331e.pdf
 Single-Phase Square-Wave and/or Pulse-Width-Modulated (PWM) Inverter

  • Obtain an AC voltage from a DC source (either 12VDC or 24VDC)
  • Household output voltage - 220V / 50Hz
  • Rated output power of at least 100W, inverter output should light up a 100W bulb (i.e., lamp acts as a resistive load)
  • Square-wave and/or PWM (bonus point) operation
  • Operation with different type of loads - a single-phase permanent-split capacitor induction motor, compact fluorescent lamp, etc. (bonus point)
