Abstract

The invention discloses a time-base circuit direct current voltage-multiplying device which is formed by a 12 volt direct-current power supply, a multivibrator circuit, a voltage-multiplying rectifying and filter circuit, a voltage regulator circuit, an electronic filtering circuit and a voltage-multiplying output terminal. The time-base circuit direct current voltage-multiplying device is characterized in that the multivibrator circuit is formed by a time-base circuit integrated circuit (IC) 1, resistant R1, resistant R2 and a timing capacitor C1, and a type selected by the time-base circuit IC 1 is NE 555. The conditions that an auxiliary power supply is added to the device, the device is limited because of geometric dimensioning, or a plurality of sets of power supplies are not convenient to arrange for the device during outdoor work are mainly solved through a low-voltage power supply boosting method. A disclosed circuit structure is varied and complex. Common time-base circuits are adopted by the circuits of the time-base circuit direct current voltage-multiplying device as core components, resistor-capacitor components are adopted by a peripheral circuit, and the direct current boosting goal is achieved. The time-base circuit direct current voltage-multiplying device has the advantages of being simple in circuit structure and free of debugging.

Description

technical field [0001] The invention belongs to the technical field of electronics and power supply, and relates to a DC voltage doubler device for a time base circuit. Background technique [0002] The commonly used step-up regulator integrated circuit is MC34063 (DC / DC), which is used in many occasions, such as: adding auxiliary power to the equipment, or because the geometric size of the equipment is limited or it is inconvenient to set up multiple sets of power supplies or In the case of outdoor emergency charging, etc., low-voltage direct current is often used to solve the problem by boosting the voltage.
