PV inverters convert DC to AC power using pulse width modulation technique. There are two main sources of high frequency noise generated by the inverters. One is PWM modulation frequency & second originates in the switching transients of the power electronics switching devices such IGBTs.
An inverter is an electronic device that can transform a direct current (DC) into alternating current (AC) at a given voltage and frequency. PV inverters use semiconductor devices to transform the DC power into controlled AC power by using Pulse Width Modulation (PWM) switching.
There are two main sources of high frequency noise generated by the inverters. One is PWM modulation frequency & second originates in the switching transients of the power electronics switching devices such IGBTs. This component is mainly attenuated by the LC lter and the transformer.
The PWM, SVM and SHE are the most commonly used modulation techniques 37, 40, 41, 42, 43. As the power dissipation across the switches is the main concern in MLI based high power grid-tied PV application, so to enhance the efficiency of MLI the multicarrier sinusoidal PWM schemes are primarily used.
