Title: Power controlling circuit in electric cleaner
Inventor: MATSUSHIRO TADASHI
IPC: H02P25/10
Filed: 1987-12-23
Abstract: PURPOSE: To improve accuracy in setting output potential of an electric fan motor and acurately control the output by using two differential amplifiers for a magnetism sensing element and setting two variable resistors for adjustment between the amplifiers. CONSTITUTION: When the volume of air sent by electric fan 6 varies, a valve 18 opens or closes. Then, a se the distance between magnet 17 and magnetism sensing element 19 varies, and the output of magnetism sensing element 19 changes. The valve 18 closes and output of sensing element 19 is maximized. As for a first amplifier 41, if input difference is large, output potential from fiducial point D becomes large, and the potential between point A and point D is maximized. The first variable resistor 46 should be adjusted to make the potential of point B equal to that of point A. Since a second amplifier 49 gets the same amount of input, the power of electric fan 6, which is determined by difference detection circuit 10 and phase control circuit 11, is maximized.  Conversely, if the valve 18 opens wider, the output of magnetism sensing element 19 reduces and the potential between point A and point D also reduces. If the potential between point A and point C is set at 0.6V by adjusting a second variable resistor 47, for example, the power of electric fan 6 is minimized.

Abstract: PURPOSE:To eliminate instable operation in high frequency region due to a compensation circuit by compensating for the high frequency components of control current through a second compensation circuit, blocking current flowing into a control circuit by means of a counterflow blocking element, and shunting counterflow of a saturable reactor by means of a shunt circuit. CONSTITUTION:A circuit comprising a capacitor C11 and a resistor R12 is arranged in a compensation circuit 14 in order to compensate for the high frequency components, damped through a compensation circuit 13, of a control current produced from a control transistor TR2. Resistors R3 and R12 are connected for the impedance of a transformer T and a saturable reactor SR thus lowering Q of the saturable reactor SR. Since the control current is shunted by means of a shunt circuit 15, the voltage.time product of the saturable reactor SR decreases and the output current increases. Since the reverse recovery current of a commutation diode D1 is also shunted, the voltage.time product based on the reverse recovery current is decreased.
