徴とするＤＣ−ＤＣコンバータの並列運転方式。[Scope of Claim for Utility Model Registration] In a device in which a plurality of switching type DC-DC converters that input a DC current and output a DC current of a predetermined voltage are connected in parallel, the DC-DC converters are sequentially connected in a chain type, A parallel control connection line that coordinates the operation of each connected DC-DC converter, and an upper limit threshold frequency fH and the operating DC
- Threshold storage means for storing a lower limit threshold frequency fL i corresponding to the number of DC converters; inputting the switching frequency of DC-DC converter #1 which is the starting end of the parallel control connection line; An operation control means for increasing or decreasing the number of DC-DC converters to be operated based on each threshold frequency stored in the value storage means and the number of operating DC-DC converters; If the frequency is equal to or higher than the upper limit threshold frequency stored in the means, a start signal is sent to an end of an operating DC-DC converter connected in the chain to instruct the start of operation of an adjacent DC-DC converter, and the lower limit is set. If the frequency is below the threshold frequency, the chain-connected D
A parallel operation method for DC-DC converters, characterized in that a stop signal is sent to an operating end of the C-DC converter to instruct it to stop operation.
