Multi-output boost rectifying circuit

Abstract

The invention relates to a multi-output boost rectifying circuit, in particular to a single-phase bipolar multi-output power supply, a three-phase unipolar or bipolar multi-output power supply and a multi-phase unipolar or bipolar multi-output power supply which are composed of diodes and capacitors, and belongs to electronic circuits or power circuits. The multi-output boost rectifying circuit is divided into four forms, namely a single-phase form, a two-phase form, a three-phase form and a multi-phase form; the single polarity is divided into positive polarity and negative polarity, and the double polarity is divided into symmetry and asymmetry; the series capacitor is also divided into two structural types of odd series and even series, and two forms of capacitor series connection and capacitor star connection are provided for connection. The bipolar multi-output boost rectification circuit is composed of two multi-output boost rectification circuits with different polarities. The three-phase or multi-phase boost rectification circuit is composed of a central capacitance column, a cross-linked diode column and a peripheral capacitance column, and the ripple pulsation of the power supply voltage is small. The multi-output boost rectification circuit has great practical value in occasions such as a G-type linear power amplification circuit and a multi-level inverter circuit.

But both of these circuits are unipolar sorting circuits and cannot provide positive and negative bipolar power supplies

[0005] Due to the complexity of the three-phase power supply, it is impossible to simply use single-phase boost rectifier circuits connected in series or in parallel to realize a three-phase boost rectifier circuit, so there is no three-phase boost rectifier circuit at present, let alone bipolar multiple Output three-phase boost rectifier circuit, it is valuable to study low-cost multi-output three-phase boost rectifier circuit with better performance
