Title: PARTIAL POWER CONVERTER (PPC) IN AN ELECTRICAL ENERGY SYSTEM
Abstract:
The invention relates to a partial power converter (PPC) in an electrical energy system, which comprises an input capacitor connected in parallel to an energy source vpv and connected to a primary winding of a transformer, the primary winding being connected in series to a metal oxide semiconductor field effect transistor (MOSFET) M1. According to the invention, two secondary windings Ns1 and Ns2, both with the same number of turns, are each connected in series by means of a terminal to respective diodes D1 and D2, said diodes D1 and D2 being connected to the respective ends of an output capacitor Cdc. The other terminal of the secondary winding Ns1 of the transformer is connected to one of the terminals of the primary winding, while the other terminal of the secondary winding Ns2 is connected to one of the terminals of the transistor M1, the output capacitor Cdc acting as a link for connecting to a following stage.
