Three-tube type full wave rectifier

Abstract

The invention provides a three-tube type full wave rectifier, which is composed of a voltage dropping capacitor C1, positive and negative half wave rectifier diodes D1 and D2, a negative half wave energy storage inductor L, an energy storage output diode D3, a voltage dividing filter capacitor C2, a voltage regulating tube VS and a load RL. Three diodes and one inductor replace a four-tube rectifier bridge for realizing full wave rectification, and the energy consumption and the size of the rectifier are reduced.

Description

Technical field: [0001] The design of the three-tube full-wave rectifier is an AC rectification power supply. technical background: [0002] In the rectification power supply circuit, we know that under the condition of single-phase transformer-free conversion from AC to DC, a bridge rectifier circuit is required to obtain a full-wave waveform current, and four diodes are used for bridge rectification. The half-wave current has to flow through two rectifier diodes, the rectification consumes a lot of energy, and the diode needs to use a heat sink to dissipate heat. The heat sink is large in size, so the rectifier not only consumes a lot of energy, but also cannot be small. Can we reduce the energy consumption and volume while achieving full-wave rectification output under the condition of reducing the number of diodes? This is our goal.

[0002] In the rectification power supply circuit, we know that under the condition of single-phase transformer-free conversion from AC to DC, a bridge rectifier circuit is required to obtain a full-wave waveform current, and four diodes are used for bridge rectification. The half-wave current has to flow through two rectifier diodes, the rectification consumes a lot of energy, and the heat sink is used to dissipate heat from the diodes. The heat sink is large in size, so the rectifier not only consumes a lot of energy, but also has a large volume.
