Title: Pwm control circuit
Inventor: OKADA KAZUHIRO
IPC: H02M7/48
Filed: 1987-05-29
Abstract: PURPOSE:To effect push-pull operation, by driving a pair or two sets of switching elements by a signal, whose pulse width is controlled, respectively and independently. CONSTITUTION:An inverter is constituted of an inverter transformer PT, main transistors Tr3, Tr4 for switching, current transformers T1, T2, current detecting circuits DET1, DET2 and a pulse width control (PWM) circuit. The PWM circuit controls the push-pull operation of an integrated circuit IC1 as well as the single end operation of the integrated circuits IC2, IC3 and connects the CT terminals of respective IC2 with each other, then, grounds them through a capacitor CT. The synchronizing operation of these three ICs is effected under the control of the main IC1. The push-pull driving of switching transistors Tr3, Tr4 is effected by putting the transistors ON, OFF by the output of the IC1 under push-pull operation alternately. Further, a voltage having a pulse width inversely proportional to the collector currents of these IC2, IC3 is outputted, whereby the independent PWM controls of the transistors Tr3, Tr4 may be effected by these outputs.

IPC: G11B20/10
Filed: 1980-09-26
Abstract: PURPOSE:To automaically reset a counter in case when operation of the counter is abnormal, by always detecting the difference to two address counters by a subtracting circuit, and resetting the counter when its result has got out of a prescribed value. CONSTITUTION:An address of an RAM1 is obtained, for instance, by adding values of a write address counter 7 and a W-ROM4 for providing a write interleave, etc. with an adder 2. A write address clock 13 and a horizontal synchronizing signal fix the phase by a double vertical synchronizing period. As to a readout address clock 14, too, the phase is decided in the same way, and the number of clocks is both 490 pieces. Accordingly, subtraction results of addresses of the point A and A' become equal. Other parts are all the same. In this case, an abnormal state denotes that a difference between values of the address counters has exceeded the range of (a) or (b). A reset operation is always executed at this point through a reset synchronizing circuit 10. According to such constitution, when operation of the counter is abnormal, it is reset automatically.
