Micro-Inverters: Design aspects
In this video there are presented some design aspects for solar micro-inverters. First you get to know what a micro-inverter is: a DC / AC converter which links one single panel from the roof top to the AC mains. Later on, the main topologie families are explained: Current source inverter and voltage source inverter. Regarding these topologies the main design aspects for low cost, high reliability and high efficiency are shown by selecting the right parts from Infineon.
