Filed: 1981-07-27
Abstract: PURPOSE:To facilitate the control with high reliability and to reduce the electric loss, by putting a serial circuit of the collector and emitter of a control transistor between an emitter circuit of a transistor in a bias oscillating circuit and an earth. CONSTITUTION:A power supply E is connected directly to a bias oscillating circuit 1 via a resistance R3, and a serial circuit of a resistance R2 and the collector and emitter of a control transistor TRQ6 is connected between the emitter of a TRQ1 and an earth. Thus the base current of the TRQ6 is controlled. That is, a base current is supplied to the base of the TRQ6 through a terminal (e), and the TRQ6 conducts to actuate the circuit 1. The working of the circuit 1 is discontinued when the base current is cut off. The loss of the base current is small since the TRQ6 has an npn structure. In such way, the control is facilitated with high reliability.

CONSTITUTION:When a test pattern is applied from a test pattern generating part 12 to the element 11 to be measured through a driver 13, a current flowing to a termi nal VSS of the element 1 is converted by a comparator 22 and a resistance 23 into a corresponding voltage value, which is compared 24 with the decision level of a power source 24, so that the comparison output is sent to a decision display circuit 20 and an AND gate 21. Further, the propriety of the high-low level of the output signal of the element 11 is decided by comparators 151 and 152 on the basis of the expected value pattern signal SP of the generating part 12 and when the level does not reaches a specific value, that is displayed on a circuit 20. On the other hand, when the output of the element 11 is a specific value and a specific time is already elapsed after the output of the comparator 24 exceeds the decision level, that is detected by a gate 21 and the generating part 12 is forced to finish the current test pattern under execution and move to the next pattern.

Title: System for restarting voltage inverter device
Inventor: KUROIWA AKIHIKO
IPC: H02M7/48
Filed: 1994-05-31
Abstract: PURPOSE:To restart safely a voltage inverter device, by limiting the discharge current during a predetermined term from a DC capacitor to an AC motor when making the inverter device restart in a short term after its stopping and making the speed of the AC motor recover. CONSTITUTION:After an instantaneous service interruption or a fault recovery, the functions of a converter 10 and an inverter 13 are restarted. Then, by the voltage difference between a capacitor 12 and a motor 14, a discharge current flows quickly from the capacitor 12 to the motor 14, and a current limiting command signal is generated from a comparator 28 when the output current of the inverter 13 exceeds the value set by a setting device 27. Subsequently, the inverter 13 is brought into OFF-state by its pulse distributing circuit, and a rush current flowing from the capacitor 12 to the motor 14 is reduced. The inverter 13 is returned to ON-state after the current limiting command is made off and a predetermined time elapses therefrom. When the inverter 13 is again brought into ON-state and the discharge current exceeds the limiting value, the current limiting signal is generated, and this operation is repeated. Thereby, the inverter 13 can be restarted safely without any protecting operation from its overcurrent.
