Title: Motor current controller
Inventor: IMANAKA AKIRA
IPC: H02P21/00
Filed: 1989-06-23
Abstract: PURPOSE:To prevent a current response from lowering without generating the overshoot of current also in a range, where a voltage control factor is larger than 1, by providing an electronic switch for compensating the delay of the integral control element of a current controller at the time of the sudden change of a current command value. CONSTITUTION:Primary current controllers 33, 34 are composed of integrating circuits, limiter circuits for switching a limiter value by a switching signal, proportioning circuits and addition circuits. An electronic switch 31 inputs the deviation signal 14a of a d*-axis primary current and sends the switching signal to the limiter circuit of the current controller 33 when the absolute value of the deviation is more than a predetermined value, i.e., in a transient state. Thus, the limiter value of the limiter circuit is limited to be switched to a normal limiter value in a steady state. In this manner, it is possible to prevent the overshoot of current accompanying the delay of an integral action in the transient state.

Title: Delay circuit
Inventor: SAITOU TAKASHI
IPC: H03K5/04
Filed: 1983-09-05
Abstract: PURPOSE:To change delay times of the rise and the fall of a pulse signal independently of each other by using an open emitter or open collector transistor (TR) as an output TR of a comparator (COM). CONSTITUTION:When an input signal rises in a COM1A using an open emitter TR as the output TR, the output TR of the COM1A is made conductive, and an output impedance is small, and therefore, an input of the second COM2A has a waveform (d) and is compared with a reference voltage at a point (e), and the result is outputted from the COM2A. When the input signal falls in the COM1A, the output impedance of the COM1A is large, and the input of the COM2A falls by the time constant due to a resistance 21 and a varicap 5 as shown by (d) in the figure and is compared with the voltage at the point (e), and an output (f) is outputted from the COM2A. When a reverse bias voltage VB is changed, the capacity is changed to control the delay time.
