Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To automatically detect short circuit between taps owing to malfunction and to realize safety correspondence by permitting a switch controller to open an interruption switch by means of an overheating signal or an abnormal current signal. SOLUTION: A temperature monitor part 11 detects the temperature rise of a transformer 3 with the temperature sensor 16 of a thermistor and the like. When it exceeds a reference temperature which is set, short circuit is considered to occur between the taps and the overheating signal is outputted. A current monitor part 13 monitors current for the respective taps. When one tap current exceeds reference current, the abnormal current signal is outputted. When the overheating signal is outputted from the temperature monitor part 11, and the abnormal current signal is outputted from the current monitor part 13, the switch controller 15 inputting the signals opens the interruption switch 5. Thus, the circuit of a secondary side coil 6 is detached and power consumed in a short circuit between the taps becomes invalid power.

Title: Dc-ac inverter circuit
Inventor: KITANO SABURO
IPC: H02M7/537
Filed: 1989-03-29
Abstract: PURPOSE:To protect components of each circuit surely without damaging in case of AC output short-circuit by connecting a base current supply circuit to a DC input terminal only in case of closing of DC input power supply. CONSTITUTION:One end of a current supply winding N3 and a starting switch SW provided with a push-button P are connected to a base of the first switching transistor Q1. An inverter circuit is not actuated by closing only DC power supply to DC input terminals 11 and 12, but the circuit starts by pushing the push-button P to turn a starting switch ON. After that, even if the push-button P is released to turn the starting switch SW OFF, the inverter continues operations. When short circuit caused by something is made between AC output terminals on the secondary side, an induced voltage of a base current supply winding is lowered to stop immediately operations of the inverter. According to the constitution, the damage, over-heating and combustion can be prevented in case of short circuited output, and cost reduction and miniaturization can be achieved.

Abstract: PURPOSE: To restrict the abrupt variation of the decelerating torque of an induction motor against braking torgue increasing rapidly in the vicinity of low speed by continuously reducing the current standard at DC braking time.  
     CONSTITUTION: When a signal f of reverse polarity with respect to the current standard of a signal e is applied to an arithmetic amplifier AMP2, an exponential fucntion singal of reverse polarity with respect to the standard e is applied through a resistor R23 to the amplifier AMP 2 by the operation of a resistor R22 and a capacitor C21 at the input of the amplifier AMP2 to thus cause the amplifier AMP2 to produce an output signal of exponential continuous signal as a DC braking current standard. When an induction motor is thus decelerated by means of DC braking, the current standard is continuously reduced with respect to the braking torgue abruptly increasing in the vicinity of low speed thereof to thereby restrict the abruptly increasing braking torque.
