Abstract:
1. A cogeneration system having a generator unit that generates DC power, an internal combustion engine for driving the generator unit, a battery that stores DC power for starting the engine, and an inverter that inverts the DC power generated by the generator unit to AC power, such that the inverted AC power of the generator unit is supplied to an electrical load, while heat exhausted by the engine is supplied to a thermal load, said cogeneration system comprising: a solar unit that generates DC power by converting radiant energy of sunlight into electrical energy; a DC/DC converter that boosts the DC power stored in the battery, and a switch for selectively choosing one of the battery and the solar unit to be connected to the inverter through the DC/DC converter further including: a selector that selects one of the DC power generated by the solar unit and the generator unit to be connected to the inverter in response to thermal load demand and electrical load demand.
