IPC: H02P6/28
Filed: 2001-11-21
Abstract: <P>PROBLEM TO BE SOLVED: To achieve lower power consumption by expanding an unsaturated operation region of an output transistor without being affected by a load current.  <P>SOLUTION: A supply current to an output transistor group 1 is controlled by a voltage comparison means 6 so that the collector voltage of the output transistor group 1 is not saturated. Further, for preventing saturation, the emitter of the output transistor group 1 is connected to a voltage comparison means 20. The voltage of a current detection means 3 is increased with the increase of the base current of the output transistor group 1, and the output of the voltage comparison means 20 is increased corresponding to the input voltage. Then, if the differential voltage with an output of a minimum value detector 4 is Va>Vb, the voltage comparison means does not transmit the current to a current addition means 8. If Va<Vb is established, the base current of the output transistor group 1 is decreased upon transmitting the current corresponding to the differential voltage. Vce (saturated) of the output transistor group 1 is secured, and the device can be controlled without being saturated.  <P>COPYRIGHT: (C)2003,JPO
