Abstract
PURPOSE:To suppress the loss at the whole operation areas by detecting the low voltage side current, judging either one of two chopper section is to be functioned on the basis of the level to be detected and perform the operation. CONSTITUTION:A current reversible chopper is used for a battery power storage system and is constituted of a battery 1, a DC reactor 21, chopper sections 22A-22B, diodes 23A-23B, a smoothing capacitor 24 and the like. Each of choppers CH1-CH2 is driven with ON and OFF at the output of the pulse amplifiers 13A and 13B by using a pulse generation circuit consisting of a phase shifter 11, a pulse dirstributor 12 and pulse amplifiers 13A and 13B. At this time, the comparators 14A-14B and the AND gaters 15A-15B are added to the pulse generation circuit, and a detector 6 to detect the low voltage side DC Io is added to the main circuit side. Accordingly, all the current reversible chopper can be operated in a whole operation area.
