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...

Problems solved by technology

[0005]Multi-resonant circuit is a circuit that combines the advantages of series and parallel resonance, but this circuit presents multiple resonance processes in the working mode due to the increase of resonant elements. It makes the design and optimization of circuit parameters very complicated and cumbersome. At the same time, it cannot solve the problems of the system closed-loop stability design when the input voltage range is wide and the load changes greatly, and the output voltage is stable under light load.
