Three-phase solar converter for mains and island power operations adapts voltage levels from DC voltage generated by solar cells to the public mains power supply by raising and converting power.

摘要

A solar converter is fed by a solar cell module (1). Input voltage of the solar converter is buffered by an input capacity (2) and fed to a converter (3) in a B2 bridge circuit (5). A high-frequency transformer (4) adapts, usually raises, KHz DC voltage from the solar modules. A non-controllable rectifier in a B2 bridge circuit is wired to an RC snubber (6) to reduce overshooting during changeover procedures.
