Pulse-width-modulated (PWM) wave inverter
What is Pulse-width-modulated (PWM) wave inverter?
A power inverter producing a nearly sinusoidal voltage, with very few current harmonics. PWM technology is used in most modern battery chargers and charge controllers. It is a function of sending out short pulses instead of applying a steady direct current voltage to a battery. State of charge of the battery influences the width of the pulses.
