Title: Circuit turned on and off with zero volt
Inventor: YAMAMOTO HIROSHI
IPC: H03K17/13
Filed: 1987-01-29
Abstract: PURPOSE:To reduce the occurrence of noise even if a circuit is repeatedly turned on/off, by triggering a triac near the zero point of an AC supply voltage at the time of first trigger and detecting the voltage between both ends of the triac to perform a required operation after triggering the triac once. CONSTITUTION:A terminal voltage detecting circuit which outputs a signal when the voltage between both ends of a triac 2 connected to an AC power source 1 through an inductive load 8 is higher than a set value, the first transistor TR 14 which is turned on/off by the output of the detecting circuit, the second TR 15 which inverts the output of the first TR, the third TR 17 which inverts the output of the second TR to flow the gate trigger current of the triac, a normally closed switch circuit 13d which is connected to the collector of the first TR and the base of the third TR, and a comparator 18 which controls the third TR of the switch circuit are provided. When the output of the comparator is turned on, the switch circuit is opened by turning-on of the third TR; and when it is turned off, the switch circuit is closed. Thus, the generated noise is minimized even if the circuit is repeatedly turned on/off.

Title: Protecting circuit for dc/dc converter
Inventor: AISAKA TORU
IPC: H02M3/28
Filed: 1985-02-06
Abstract: PURPOSE:To perform a projection of a DC/DC converter without melting of a fuse or rough chip loss of a contactor by detecting the incoincidence of a gate signal of a controller to ON/OFF of a switching element of a main circuit and stopping the operation of the converter. CONSTITUTION:Gate signals 2a, 2b of the outputs of a voltage controller 2 are applied to an OR circuit 7, and the output and the output of a comparator 5 are input to an incoincidence detector 8. The detector 8 inputs an incoincidence signal as a clear signal of a counter 10 only during a period that the logic levels of two inputs are incoincident. The counter 10 counts the outputs of a clock circuit 11 as a clock input. The output of an FF circuit 12 becomes H level by the output of the counter 10, thereby stopping the gate signals 2a, 2b of switching elements S1, S2 of the controller 2, and a contactor CTT1 is simultaneously opened.
