Abstract
The present invention provides a solar power converter with isolated bipolar full-bridge resonant circuit. This solar power converter system of the present invention have isolated two-stage full-bridge resonant circuit having a full-bridge resonant converter unit for solar power converter among fixed by uncontrolled phase shift controlled full bridge resonant converter unit, so as to all power switches of the full bridge resonant converter unit in any load can reach zero voltage switching, not only can improve light-load efficiency, the scope for efficiency under full load variation of both improvement and helpful.
