摘要： PROBLEM TO BE SOLVED: To provide a signal transmission device for transmitting propagation targeted signal (input signal Vin) of binary values in logic "H" and logic "L" states, from either a high-pressure system or a low-pressure system to the other, capable of suitably prolonging the lifetime of a photocoupler 30. SOLUTION: The input signal Vin includes a pulse signal having a period shorter than the period in logic "H" and logic "L" of an output signal Vout which serves as a drive signal for driving an inverter. Specifically, the input signal Vin includes a single pulse signal for defining the rising edge of the output signal Vout and two pulse signals for defining the falling edge. The pulse signal of the input signal Vin causes the photocoupler 30 go into an ON-state, and the inverted signal V1 by the inverter 52 becomes equal to the input signal Vin. Furthermore, a D flip-flop 58 outputs the drive signal Vout. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To allow a stable and high-accuracy constant-voltage control at the time of no load or light load.SOLUTION: In a driving-signal generation circuit 24 that receives a PWM control signal and outputs a PWM driving signal, when a voltage Vb changes from H to L, a charging current flows into a capacitor 30 from a power-supply line 27 through a transistor TP2 and a resistor 29, so that the rising gradient of a voltage Vc decreases and inversion timing to H is delayed. When the voltage Vb changes from L to H, the resistor 29 does not intervene in a charging path of the capacitor 30, so that inversion timing to L is not delayed. The providing of a delay circuit 31 narrows the H pulse width of the voltage Vc and can output an extra narrow on-pulse.
