Title:
INVERTER HAVING EXTENDED LIFETIME DC-LINK CAPACITORS
Document Type and Number:
WIPO Patent Application WO/2012/119232
Kind Code:
A8
Abstract:
An inverter having extended lifetime DC-link capacitors for use with a DC power source such as a photovoltaic panel is described. The inverter uses a plurality of switchable capacitors to control the voltage across the capacitors. The expected lifetime of the capacitors can be extended by disconnecting unnecessary capacitors from a voltage. The capacitors may be periodically connected to a voltage in order to maintain an oxide dielectric layer of the capacitor.
