A PWM (Pulse Width Modulation) Inverter is a device that converts direct current (DC) to alternating current (AC) by modulating the width of the pulses in the output signal. It generates a series of pulses with varying widths to create an AC waveform that closely approximates a sine wave.
[pdf] Inverter air conditioners are energy-saving air conditioning units equipped with an inverter-driven compressor. An inverter-driven compressor has the ability to increase or decrease its rotational speed thereb.
[pdf] Set the multimeter to AC voltage mode. Measure the voltage at the inverter’s input terminals. Confirm that the reading matches the inverter’s rated input voltage range (e.g., 220V, 380V, or 480V AC depending on the model).
