CHARGE-DISCHARGE DEVICE WITH EQUALIZATION FUNCTION USING BOTH CONVERTOR AND MULTI-STAGE VOLTAGE DOUBLER RECTIFIER CIRCUIT

摘要

It is an object of the present invention to provide a charger which can be charged while eliminating the voltage deviation of the charge cell and which does not need to design the current capacity at least for the circuit section which is responsible for at least the charge cell voltage equalization, And a discharge unit. Converter, an input circuit, and a multi-stage voltage rectification circuit. The voltage equalization function is realized by connecting the element to which the voltage of the converter''s sphere waveform is applied to the multi-stage voltage rectification circuit through the input circuit, and the output part of the converter is connected to the multi-stage voltage rectification circuit to implement the charge / discharge function.
