Title: Means and method for preventing rush current
Inventor: SUZUKI TOSHIYASU
IPC: H02H7/16
Filed: 1990-08-13
Abstract: PURPOSE:To limit the amplitude of a main current of a transistor and to prevent a rush current by connecting a capacitor between the control terminal and a main terminal of a voltage drive type transistor. CONSTITUTION:When a power switch 2 is closed, a transistor 4 is turned OFF since the voltage of a capacitor 5 is zero. A charging current flows to a capac ity between the gate and the source of the transistor 4. As its charging current is raised, the transistor 4 starts to turn ON, and its internal resistance is re duced. the rising speed of the voltage between the gate and the source is delayed due to a cause such as an internal resistance, the contact resistance of the switch 2, etc., and it is further delayed by the charge of the capacitor 5 when the transistor 4 is conducted. The drain current of the transistor 4 is largely limited in response to the capacitor voltage, and the peak value of the rush current of the capacitor 5 is suppressed to a lower value than that before this provision.

Title: Speed control method for brushless dc motor
Inventor: NAGANUMA YOICHI
IPC: H02P6/06
Filed: 1988-08-26
Abstract: PURPOSE:To spread a speed-torque range by giving the applying timing of supply voltage enough to show a much more leading phase to induced electromotive force in the phase currents of a brushless DC motor. CONSTITUTION:A sensor generating pulses while being synchronized with the revolution section of a motor is installed, and data are extracted successively according to pulses synchronized with the speed of the motor. A synchronous pulse 29 multiples the values of cos theta and sin theta from IC memories 3, 4 by currents at every 3 deg. and conducts interval-integration at 360 deg., and clears an integrator at every 360 deg. at the time of revolution and the timing pulses of integration clear at a time when tan phi1 is obtained are acquired. A switch 13 performs the phase control of the fundamental wave components of induced electromotive force and phase currents so that a brushless DC motor attains normally the connection line of tan phi1=0 of r<1. When the motor is operated under the conditions of pi/2>phi1>0 near r=1, speed-torque characteristics are acquired. Accordingly, supply voltage is determined by speed (n) and phase voltage V1 prior to induced electromotive force so that phi1 0 and a power factor 1 hold.
