PV Array with Inverter PWM

A photovoltaic (PV) array converts sunlight into direct current (DC) electricity, but most applications require alternating current (AC). This conversion is done using an inverter, which often employs pulse-width modulation (PWM) to efficiently transform DC power into AC.

PWM in inverters works by rapidly switching the DC input on and off in controlled pulses, adjusting the width of these pulses to approximate an AC sine wave. This method ensures minimal energy loss while maintaining high power quality.

For PV systems, PWM helps optimize energy extraction from solar panels by matching the inverter's output to the grid requirements or load demand. The technique also aids in voltage regulation and harmonic reduction, improving overall system efficiency.

By leveraging PWM, PV inverters maximize power conversion, ensuring stable and clean energy delivery from solar arrays to electrical systems.
