Title: Driving circuit of switch element
Inventor: ISHII SATORU
IPC: H03K17/687
Filed: 1983-03-26
Abstract: PURPOSE:To minimize power loss with a switching element by using a serial circuit consisting of a diode and a resistance and an inductive element which are set in parallel to said diode to form a driving circuit of a semiconductor element for switching operation. CONSTITUTION:The gate driving circuits of switching semiconductor elements Q1 and Q2 consist of a serial circuit containing diodes D1 and D2 connected in the direction where the conduction is prevented for the elements Q1 and Q2 respectively and a resistance R1 and an inductive IND element L1 which are parallel to the diodes D1 and D2 as well as a serial circuit of a resistance R2 and an IND element L2. When a step type signal is impressed in forward direction to an input terminald 1, the gate voltage of the element Q1 shows the synthesization of a curve which rises up with a time constant obtained by the inter- electrode capacity between the R1 and the Q1 and a curve produced by the L1 and the inter-electrode capacity. This gives some delay to the time during which the Q1 is turned on and prevents that both Q1 and Q2 are simultaneously turned on. Furthermore the gate bias is deepened after the Q1 is turned on, and therefore the ON resistance is reduced. This attains a switching operation with small power loss.
