Patent JP-H0677800-A (JP)
Title: Insulated gate type field effect transistor, three-terminal switch, switching circuit, and resonance type power conversion circuit
Inventor: SUZUKI TOSHIYASU
IPC: H02M1/08
Filed: 1992-11-30
Abstract: PURPOSE:To quicken turning-off even with a normal turning-off driving voltage and to quicken turning-off without increasing an on/off threshold voltage. CONSTITUTION:A DC power source 2 is connected between a back gate terminal, 5 and a gate terminal 6 of an insulated gate field effect transistor TR 1 in the reverse voltage direction between the source and the back gate. In another method, a capacitance means is connected between the back gate and the gate of the insulated gate field effect TR. By these methods, the voltage between the source and the back gate is changed by turning-on/off, and the on/off threshold voltage for turning-off is higher than that for turning-on, and therefore, turning-on/off is quickened without raising the on/off threshold voltage for turning-on, that is, sacrificing the on-state resistance.
