Title: Voltage controller for cvcf
Inventor: OKATSUCHI CHIHIRO
IPC: H02M7/48
Filed: 1987-03-30
Abstract: PURPOSE:To increase the accuracy of control, by a method wherein a zone, in which frequency response is high, is controlled by a loop for controlling the changing rate of an output voltage while another zone, in which the frequency response is low, is controlled by another loop, for controlling the value of the output voltage. CONSTITUTION:A constant voltage constant frequency inverter for the control of a PWM inverts a DC current into an AC current through an inverter bridge 2 to obtain a predetermined AC power source through a filter consisting of a capacitor 4. The feedback of the output voltage of the AC power source into a control circuit is effected through a transformer 5 whereby the output voltage is controlled. A difference between the output v6 of a voltage reference generator 6 and the detecting value v5 of the output voltage V is inputted into an adder 11 through an amplifier 7. A difference between an output v12, obtained by passing a voltage reference v6 through a differentiating circuit 12 and another output V13, obtained by passing a detecting value v5 through another differentiating circuit 13, is inputted into the adder 11 also through another amplifier 4. An added value V11 is compared with a triangular wave signal from a triangular wave generator 9 to effect the control of the PWM.

Inventor: UEDA KENJI
IPC: H03K17/567
Filed: 1986-03-31
Abstract: PURPOSE:To operate the circuit for a power voltage of a wide range by connecting a Zener diode and a FET in series to a power terminal via a diode bridge, giving a voltage across the Zener diode to a detection circuit, operating the FET based on the switching output so as to supply a current to a load. CONSTITUTION:A DC or AC power supply 6 and a load L are connected in series between input terminals 1 and 2. When the detection circuit 4 detects no object, a transistor (TR) 3 is turned off and a voltage across the Zener diode D4 is applied to a gate of a FET 5 via a voltage division circuit comprising resistors R3,R4. A minute current is selected as a drain current of the FET 5 fo supply a current required for the detection circuit 4 and becomes a leakage current to a load 6. When the detection circuit 4 detects an obkect, its detection output turns on the TR 3, the gate voltage of the FET 5 rises, the drain current of the FET 5 is increased remarkably, and the load current of the load L flows to the Zener diode D3 and the FET 5 via a diode bridge 3. In such a case, the voltage across the FET 5 is very low and the residual voltage is kept lower.

IPC: B60T8/1755
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To perform vehicle attitude control, particularly for inhibiting drift-out, without deteriorating the stability of vehicle body attitude. SOLUTION: In drift-out inhibiting control (SE 3), a braking force is imparted to an inner turning front wheel to exert yaw moment which changes the attitude of the vehicle body toward the inside of turning, thus reducing the understeering tendency of the vehicle. The amount of braking force imparted to the inner turning front wheel is limited so that the wheel slip rate of the front wheel is not more than a set upper limit value σlim which is set to be a predetermined amount smaller than the maximum slip rate. The set upper limit value is set (SE5) to be smaller than those for spin inhibiting control, and is changed and set (SE6, SE7) in such a way that the greater the steering angle θH and steering speed θH', the smaller the upper limit value.
