PROBLEM TO BE SOLVED: To provide a charger which is capable of performing charging while eliminating variations in the voltages of storage cells and in which at least a circuit part responsible for equalization of the voltages of the storage cells is not required to be designed to have a large current capacity, and also to provide a charger-discharger further equipped with a discharging function in such a charger.SOLUTION: There are provided a charger and a charger-discharger comprising a converter, an input circuit, and a multi-stage voltage doubler rectifier circuit. A voltage equalization function is achieved by connecting an element in the converter to which a rectangular wave voltage is applied to the multi-stage voltage doubler rectifier circuit via the input circuit, and a charging-discharging function is achieved by connecting an output unit of the converter to the multi-stage voltage doubler rectifier circuit. |
