Design and Research of Electronic Switch based on Proteus Circumstance

At present, most of the electronic switches used have single function, raise voltage or reduce voltage, and also have step-up and step-down, it has the step-up and step-down function, but the circuit structures simple is not much. In this paper, an electronic switch which can replace the step-up and step-down circuits is designed. Three different levels of step-up, step-down and constant voltage are designed through voltage gain, the circuit solves the problem that the original small and medium power circuit can only step-up or can reduce the voltage, and realizes the function that the same circuit can not only boost the voltage but also realize the step-down function, and meets the requirement of continuous and adjustable power. Through the simulation and calculation results verify the feasibility and correctness of the design, and provide convenience for users, especially in the use of small and medium power. The voltage gain can be adjusted precisely according to the requirement, so that the voltage can reach the exact voltage value that can be adjusted continuously, thus shortening the engineering design cycle and the R & D process.
