Problems solved by technology

In the rectifier circuit, the single-phase conductivity of the diode is used to convert the alternating current into a pulsating direct current, but there are often too many ripples in the direct current voltage, which will cause certain troubles to the subsequent filtering process and increase the complexity of the circuit

Abstract

The invention discloses a rectifying circuit comprising a diode, a transformer, a capacitor and a resistor. By the one-phase electrical conductivity of the diode, an alternating current is converted to a pulsatory direct current; due to the characteristics of the diode and the capacitor, a few ripple waves exist in direct current voltage, and the filtering process becomes simpler. The output characteristic of the rectifying circuit is good, larger discharge currents can be output, and the rectifying circuit is particularly suitable for small laboratories.

Description

[0001] technical field [0002] The invention relates to a rectifier circuit, in particular to a voltage doubler rectifier circuit. Background technique [0003] In electronic systems, it is often necessary to convert the AC grid voltage into a stable DC voltage, so rectification and other links are required to achieve it. In the rectifier circuit, the single-phase conductivity of the diode is used to convert the alternating current into a pulsating direct current, but there are often too many ripples in the direct current voltage, which will cause certain troubles to the subsequent filtering process and increase the complexity of the circuit. [0004] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0005] Purpose of the invention: In view of the above existing problems and deficiencies, the purpose of the invention is to provide a rectifier circuit with a simple structure and less clutter. [0006] Technical solutio...
