Abstract

The invention provides a modularized high-pressure power supply circuit which comprises a boosting circuit, a resonance boosting isolating circuit, a voltage doubling rectifying circuit and a control circuit, wherein the voltage boosting circuit is used for boosting input low-pressure wide-range direct voltage into output direct voltage with higher relative voltage; the resonance boosting isolating circuit is connected with the boosting circuit, and is used for converting the direct voltage output by the boosting circuit into resonance alternate current to be output through voltage transformation isolation; the voltage doubling rectifying circuit is connected with the resonance boosting circuit, and is used rectifying the alternate current output after resonance change of the resonance boosting isolating circuit into direct current to conduct voltage doubling boosting; the control circuit conducts voltage close-loop control on the boosting circuit and conducts fixed-frequency open-loop control on the resonance boosting isolating circuit. Various levels of short circuit structures of the circuit are relatively fixed, low-pressure wide-range input and high-pressure high isolation multichannel output are facilitated, the precision of the output voltage is high, the control is simple, the power density is high, the modularization is easy, and the modularized high-pressure power supply circuit is particularly suitable for being used as a power supply of an MPM after the modularization.

Description

technical field [0001] The invention relates to the fields of detection technology, signal processing and electric control, in particular to an intelligent manipulator control system based on a single-chip microcomputer system circuit. Background technique [0002] The high-voltage power supply is a necessary power supply device for the microwave power module (MPM). The core unit of the MPM is the traveling wave tube amplifier. Its cathode, grid, and collector all need high-voltage power supply. In order to improve efficiency, the collector often uses multiple The step-down collector technology requires multiple sets of high-voltage power supplies, so the power supply of the entire traveling wave tube requires multiple high-voltage power supplies. MPM has the advantages of broadband, high efficiency, low noise, small size, and light weight, and has gradually become a standardized general-purpose amplifier in the fields of radar, satellite communication satellite systems, las...
