Abstract :
A single-phase 1kW transformer-less grid tie inverter is presented for supplying a domestic 230V ac mains supply from a 425V dc source such as a photo-voltaic solar panel array. Permutations of super-junction MOSFETs with SiC diodes and SiC MOSFETs are investigated. A new gate driver topology with isolation and energy recovery is presented.
