Abstract:
1. An apparatus for controlling a power converter system, the apparatus comprising: a bi-directional AC/DC converter connected to an AC power supply, a first DC/DC converter connected to a DC electricity source and having a voltage up-conversion function, a second DC/DC converter connected to an electric load (Rload) and having a voltage down-conversion function, and a controller configured to control an operation of said bi-directional AC/DC converter and said first and second DC/DC converters power as function of measured electrical parameters so as to supply said electric load (Rload) with a controlled DC voltage and power from said direct current electricity source via said first and second DC/DC converters with high priority and with electricity from said AC power supply via said AC/DC converter and said second converter with lower priority, wherein one of the first and the second DC/DC converters is controlled to conduct an input directly to an output without energy conversion to maximize energy efficiency of the converter system.
