Title: Driving circuit for current controlled semiconductor device and driving device for current controlled semiconductor device
Inventor: KARAKI TOSHIRO
IPC: H03K17/64
Filed: 2002-01-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a driving circuit for a current controlled semiconductor device in which a voltage between a base terminal and an emitter terminal can be prevented from oscillating in the case of turning-off.  <P>SOLUTION: When turning off a transistor Tr1, a carrier is extracted from the base terminal of the transistor Tr1 by carrier extraction paths M21U and D22U of a low impedance and just before turning off the transistor Tr1, the carrier is extracted from the base terminal of the transistor Tr1 by carrier extraction paths RU and M23U of a high impedance. By making large the R component of the dumping factor of an RLC resonance phenomenon on the carrier extraction path just before turning-off, in the transistor Tr1, a voltage Vbe between the base terminal and the emitter terminal is gradually lowered and the transistor is turned off. Thus, the transistor is not erroneously turned on again after turning on, and further, a current does not flow to the carrier extraction paths M21U and D22U of the lower impedance after turning-off such that the heat generation of the circuit can be suppressed.  <P>COPYRIGHT: (C)2003,JPO
