Title: Inverter device
Inventor: OGAMI MASAKATSU
IPC: H02P21/04
Filed: 1988-09-06
Abstract: PURPOSE:To obtain an inverter device, which can control an induction motor so as to obtain its output torque stable even in a low speed region, by constituting the device so as to output a torque component voltage command and an excitation component voltage command of the induction motor. CONSTITUTION:A 3-phase/2-phase converter 1 detects three-phase currents iv, iu, iw of an induction motor (not shown) and outputs a two-phase current signal corresponding to a torque component current Igamma and to an excitation component current Idelta by using an integral value of an inverter operation angle frequency command omega1*. A setter 20 outputs a value resulting from multiplying a difference between the command omega1* and a signal corresponding to the excitation component current Idelta by a positive constant K to a multiplier 3. An adder 28 adds an output signal R1Igamma of a setter 24 to an output signal L1omega1*Idelta* of a setter 27 to output, and an adder 29 outputs a signal corresponding to torque component voltage Vgamma, obtained by adding output signals of a divider 23 and the adder 28, as a torque component voltage command Vgamma* by an expression I. On the other hand, an excitation component voltage command Vdelta* is obtained by an expression II from an output signal Vdelta of a setter 25.

Title: Output circuit for semiconductor device
Inventor: FUKIAGE TAKAHIKO
IPC: H01L27/092
Filed: 1989-08-30
Abstract: PURPOSE:To improve level swing of an output signal by supplying a prescribed voltage to a control electrode of a 2nd field effect element connecting in parallel with a 1st field effect element driving an output node in response to a control signal. CONSTITUTION:Since a transistor(TR) 1 is turned on in response to a signal phi1, an output node No reaches a voltage Vcc-Vth, and since a TR 5 is turned on in response to a signal phi4, the gate of a TR 3 reaches a ground level. A signal phi3 rises to a Vcc level and the signal phi4 decreases to a ground level at times t3-t4. A gate of the TR 3 reaches a voltage (Vcc+alpha) over a Vcc+Vth with the bootstrap effect by the signal phi3 supplied to a capacitor 6. Thus, an output voltage VouT rises again up to the voltage Vcc at the times t3-t4. Thus, the output voltage VouT having a voltage level Vcc improved after the time t4 is obtained.
