GATE DRIVING CIRCUIT AND BASE DRIVING CIRCUIT

摘要: PURPOSE:To reduce the power consumed by a gate driving circuit or base discriminating whether not flywheel diode is conductive and stopping on-gate current of GTO transistor(TR) to be turned on output ON current. CONSTITUTION:The 2 with 3 connected in reverse parallel thereto 1. Even when on/off command at H gate, on, since an over-driving 11 length width 12 are operated, undesired consumption 1 prevented. When ON/OFF L level, logical input off-gate 13 goes level but disadvantageous operation caused without giving any effect AND 16.
