基于PIC单片机的升压电路的研究

In the design of a capacitor charging circuit, DC110V needs to be boosted to DC400V. Consider the power supply voltage may fluctuate in actual use, the requirements in the input voltage is 77V-138V, the output can be stable in the DC400V. In the DC/DC chopper circuit, Boost circuit has the advantages of simple structure, only one switching device, has the advantages of small volume, simple structure, the advantages of higher conversion efficiency. This paper introduces a design method of Boost boost circuit, including the hardware principle and software parts of the process, and the simulation is conducted, which makes the circuit can achieve the objectives.
