PRINCIPLE OF OPERATION
The inverter converts the rated DC voltage of the battery to 120 V, 60 Hz. AC voltage.
The voltage conversion takes place in two stages. In the first stage, the rated DC voltage
of the battery is converted to a high voltage DC using high frequency switching and Pulse
Width Modulation (PWM) technique. In the second stage, the high voltage DC is
converted to 120 V, 60 Hz. sine-wave AC again using PWM technique. This is done by
using a special wave shaping technique where the high voltage DC is switched at a high
frequency and the pulse width of this switching is modulated with respect to a reference
sine-wave.
