Patent ID: 10624243

Abstract:
An inverter for converting DC voltage into AC voltage, in particular a photovoltaic inverter for high power densities, in particular 250 W/dm3 to 500 W/dm3 power densities, has at least one DC input, an AC output, a heat sink, a printed circuit board, a DC disconnector, a DC-DC converter, an intermediate circuit, a DC-AC converter and a housing with a front cover and a basic shell. The electrical components of the DC-DC converter, intermediate circuit and DC-AC converter are combined into subassemblies. At least the DC disconnector and the subassemblies of the DC-DC converter, intermediate circuit and DC-AC converter are directly arranged on the circuit board in a U-shaped manner corresponding to the energy flow direction from DC input to AC output. The circuit board is arranged with the component side facing the base (65) of the basic housing shell and with the opposite side on the heat sink.
