Title: Inrush current preventive circuit for voltage type inverter
Inventor: TOMINAGA RYUICHIRO
IPC: H02M7/06
Filed: 1995-03-13
Abstract: PURPOSE: To prevent the permanent magnet in a DC reactor from being demagnetized by additionally providing a series circuit of a diode and an inrush current suppressing resistor. CONSTITUTION: A main circuit contactor 3 is driven through a contactor control means 6. When an inverter control means 8 decides that the charged state of a smoothing capacitor 5 is lower than a reference level, the main circuit contactor 3 is opened to interrupt the inrush current flowing into a DC reactor 11 perfectly. When the inverter control means 8 decides that the charged state of the smoothing capacitor 5 is higher than the reference level, i.e., the capacitor 5 is charged sufficiently, the main circuit contactor 3 is closed to short-circuit an inrush current suppressing resistor 2 thus conducting the DC reactor 11 with the smoothing capacitor 5. A diode 4, connected in series with the inrush current suppressing resistor 2, prevents a circulation current from flowing into the parallel circuit of the DC reactor 11 and the inrush current suppressing resistor 2.

IPC: H03F3/45
Filed: 1986-04-09
Abstract: PURPOSE:To lower the minimum power supply voltage required for the normal operation by providing a voltage clamp stage connected to an inverting input terminal to the 2nd amplifier stage connected to the output of the differential amplifier stage having the inverting input and a noninverting input and connected to the output terminal. CONSTITUTION:An input signal is impressed between the inverting input terminal 1 and the noninverting input terminal 2, amplified by a differential amplifier stage 4 and inputted to the 2nd amplifier stage 5. The output signal of the amplifier stage 5 is outputted to an output terminal 3 and inputted to a voltage clamp stage 6. When an output signal voltage reaches neary 0.7V at the terminal 3, a base-emitter of a transistor (TR) Q6 is forward-biased and the current to the terminal 1 is supplied from the power supply through the TR Q6 and negative feedback is applied to the terminal 1, then the output voltage is clamped at nearly 0.7V. When the output signal voltage reaches nearly-0.7V, since a TR Q7 is activated, the output voltage is clamped to nearly-0.7V. Thus, the minimum power voltage required for the normal operation is nearly 1.8V being twice the sum of the emittervase voltage of the TR Q7 and the saturation voltage of a TR Q5 and the voltage is lower than that of a conventional circuit.
