Abstract: A method and inverter (2, 27) for converting a DC input voltage supplied by a DC source (9), which is in particular a solar cell array, into a 3 -phase AC output. For each phase (R, S, T) the DC input voltage is converted to a DC output voltage (DCR, DCS, DCT) with a specific waveform. The waveforms of the three DC output voltages are identical, shifted in time by 120° to each other and they are such that by subtracting any two of them a sinusoidal waveform is obtained. The waveform of each DC output voltage may comprise a first portion of 1/3 or 120° of the AC output cycle with an amplitude of zero and a subsequent second portion of 2/3 or 240° of the AC output cycle during which the DC output voltage has a non-zero amplitude.

Abstract: The present invention is related to an electrical energy conversion circuit device (190), a method (600) of operating an electrical energy conversion circuit device, an electrical apparatus (500) and a computer program. The circuit device (190) allows earth connection and comprises two parallel connected buck-boost converters for converting a direct input voltage (110) into a direct output voltage (120). The converters are adapted to generate two phase-shifted currents (131, 141) that are received by an output capacitor (160). Due to the phase-shift, a current ripple is reduced. The direct output voltage (120) and the direct input voltage (110) preferentially have a common potential (114) and are of opposite polarities. Therefore, a second voltage of high magnitude, the sum of the direct input voltage (110) and the direct output voltage (120) is also provided.

Abstract: The present invention relates to a power converter architecture and its operation principle that supplies an electric load with a controlled direct voltage from both a local direct current electricity source as well as an alternating current (AC)mains with maximum power conversion efficiency. For the case that the local electricity source can not provide enough electricity to the local load it is additionally supplied with electricity from the AC mains. In other case electricity is also feed into the AC grid when a local source can provide more electricity than needed to supply local loads.
