Abstract: A solar power conditioner includes: a synchronous controller; and electric power converters connected in series with each other and arranged at panel groups, respectively. Each electric power converter executes a MPPT control for tracking a maximum power point of an output electric power of the panel group, and converts a voltage and a current of the output electric power of the panel group. The synchronous controller synchronously controls the electric power converters to superimpose converted voltages in series, the converted voltages outputting from the electric power converters, so that the electric power converters output a predetermined pseudo sine wave voltage or a predetermined alternating current voltage.

Abstract: A semiconductor device includes: first and second semiconductor elements each having two electrodes respectively disposed on two surfaces; two first terminals respectively connected to the two electrodes of the first semiconductor element and arranged side by side in one direction; two second terminals respectively connected to the two electrodes of the second semiconductor element, and arranged side by side in the one direction to be adjacent to the two first terminals; and a sealing resin portion covering the first and second semiconductor elements and the first and second terminals in a state where facing surfaces of the first and second terminals are exposed from the sealing resin portion. The facing surfaces of the two first terminals have different area ratios, the facing surfaces of the two second terminals have different area ratios, and one of the first terminals is arranged adjacent to both the two second terminals.
