PROBLEM TO BE SOLVED: To provide a multichannel charge and discharge power source which can reduce the number of components and improve reliability. SOLUTION: In this multichannel DC power source, a means which converts DC voltages to AC voltages en bloc, and a means which distributes the converted AC voltages are installed, and insulation and an AC converting means for level conversion are lumped together, so that the number of components can be reduced and reliability can be improved as compared with the case that an AC converting means is installed for each conversion circuit.
