Title:
複合半導体スイッチ装置
Document Type and Number:
Japanese Patent JP5776843
Kind Code:
B2
Abstract:
A composite semiconductor switching device includes: a first semiconductor element that incurs switching losses when performing switching operation of turning on and off; a second semiconductor element that is parallelly connected to the first semiconductor element and incurs switching losses larger than the first semiconductor element when performing switching operations of turning on and off; and a controller that operates in order of giving a first on-command signal to the first semiconductor element, giving a second on-command signal to the second semiconductor element, deactivating the first on-command signal, giving a third on-command signal to the first semiconductor element, and deactivating the second on-command signal.
