摘要
A cooperative control method for a plurality of power semiconductor elements connected in parallel. The cooperative control method includes (1) connecting, in a daisy chain configuration, a plurality of current balance control circuits each for driving a corresponding power semiconductor element, and (2) responsive to an input to cause the power semiconductor elements to simultaneously perform switching operations, comparing current information of each power semiconductor element with that of an adjacent power semiconductor element, and delaying, using the current balance control circuits, turn-on time or turn-off time of each power semiconductor element, upon determining that the turn-on time or the turn-off time is earlier than turn-on time or turn-off time obtained from the current information of the adjacent power semiconductor element.
