Title: Control system of inverter
Inventor: HIROSE KENJI
IPC: H02P27/02
Filed: 1985-08-22
Abstract: PURPOSE:To prevent an overcurrent trip of an inverter by suppressing only an output voltage immediately after a power source is turned ON or when starting after releasing a reset, and bringing the output frequency rapidly in coincidence with the rotating speed of an induction motor. CONSTITUTION:When a power source is turned ON, a microcomputer starts operating, confirms ON and OFF of a start switch and a reset switch, and reads out a frequency set signal (ST-1-ST-4). Then, whether it is immediately after the power source ON or the start after releasing a reset is identified (ST-4A, ST-4B). Whether the output current is a limiting value or lower or not is confirmed (ST-4C). If it is the limit value or lower, the output voltage and frequency are increased according to V/F pattern as it is (ST-4D, ST-4F). If it is the limit value or higher, the output is reduced (ST-4E), the output frequency is increased (ST-4F), and the output signals are fed to a main circuit (ST-7).

Title: Oscillation control circuit
Inventor: HOSAKA TOSHIYUKI
IPC: H03L3/00
Filed: 1984-08-31
Abstract: PURPOSE:To absorb noises due to chattering or static electricity caused at the time of switch input by detecting again the switch input state at switch input and after a prescribed time is elapsed and inputting the result to a reset system. CONSTITUTION:When a switch 1 is depressed, an FF10 is reset, its Q' output 32 goes to H, the oscillation of a CR oscillation circuit starts oscillation and a clock signal 22 is outputted. The chattering with the switch 1 turned on is prevented by FFs 3, 4 and an inverter 5 by giving this signal 22 for the period up to the leading of a Q output 24 frequency-divided by FFs 17-20. Then an output 27 of a NOR circuit 6 goes to H by the falling of the Q output 24 to reset an FF7. Just after the reset, a Q' output 28 of the FF7 goes to H, an output 30 of a NOR circuit 9 goes to L and the oscillating state is maintained. Thus, noises by chattering or static electricity produced at switch input are absorbed in this way.
