費する電力をより少なくし、電源電圧の変動に対しても

が要求されて−いる。Conventional configurations and their problems In recent years, the trend has been to save energy, and efforts have been made to reduce the power consumed by controllers and to keep the current flowing through the controllers constant even when the power supply voltage fluctuates. There is a need for the development of controllers.

ランス１の一次コイルに流れる電流が低下し、二次コイ
ルに発生する交流電圧も低下して、電磁弁７に供給する
電圧も低下し電磁弁７が吸着保持できない。The current flowing through the primary coil of the pulse transformer 1 is operated by the output of the drive circuit 3 of the switching element 2. When the output of the drive circuit 3 is at a high potential VH (Fig. 2), a base current is supplied to the base of the switching element 2 through the resistor 4, the switching element 2 is turned on, and the primary coil of the pulse transformer 1 receives current from the dry battery E. flows,
Electrical energy is stored in the primary coil of the pulse transformer 1, and the output of the drive circuit 3 is at a low potential vL (second
At the time shown in Fig.), the switching element 2 is turned off, and the electrical energy stored in the primary coil fζ of the pulse transformer 1 is converted to direct current through the rectifying diode 5, charging the smoothing capacitor 6 and supplying voltage to the solenoid valve 7. and was driving. However, in the above configuration, when the electromotive voltage decreases due to consumption of the dry battery E, the current flowing through the primary coil of the pulse transformer 1 decreases, and the AC voltage generated in the secondary coil also decreases. As a result, the voltage supplied to the solenoid valve 7 also decreases, and the solenoid valve 7 cannot be held by suction.
このため、乾電池の起電力が低い時でも電磁弁７を吸着
保持できるようにパルストランス１の一次コイルに電流
を流す必要がある。したがって乾電池Ｅの起電力が充分
に高Ｌζ時には、電磁弁７の吸着保持に必要以上の電流
が流れることになり、乾電池の消耗を加速するという欠
点があった。Therefore, it is necessary to supply current to the primary coil of the pulse transformer 1 so that the electromagnetic valve 7 can be attracted and held even when the electromotive force of the dry battery is low. Therefore, when the electromotive force of the dry battery E is sufficiently high Lζ, a current larger than necessary to attract and hold the solenoid valve 7 flows, which has the disadvantage of accelerating the consumption of the dry battery.

定電流回路である。When the switching element 2 is ON, that is, when the output of the drive circuit 3 is at a high potential VH, the base potential VB of the switching element 2 is equal to the forward voltage (VF
X2). Therefore, the emitter voltage VE of the switching element 2 is the base-emitter voltage (two forward voltages) of the switching element 2 and the forward voltage V of the diode 9.
The current flowing through the primary coil of the pulse transformer 1 is determined by the forward voltage VF and the resistor 11, regardless of the electromotive force of the dry battery E. Therefore, the voltage supplied to the electromagnetic valve 7 is always constant regardless of the electromotive force of the dry battery E. Note that 8 is a constant current circuit.
