PROJECT TITLE :

Future Drives of Home Appliances: Elimination of the Electrolytic DC-Link Capacitor in Electrical Drives for Home Appliances

ABSTRACT:

This article describes the next step in the development of the house appliance motor drive-the elimination of the electrolytic dc-link capacitor and also the substitution of one with a little film. A tiny film capacitor increases total device reliability and improves the spectrum of the input current so the power factor corrector (PFC) used to satisfy existing standards on harmonic current emission will be omitted, which decreases the dimensions and cost of the appliances. This article conjointly proposes straightforward modifications to the standard vector management scheme, creating operation with pulsating dc-link voltage potential.
