Abstract

Abstract: This paper mainly introduces the design of a constant voltage circuit based on the high-end drive of PMOS and its application in the control circuit of water purifier intake booster pump. The constant voltage circuit introduced in this paper mainly includes MCU control circuit, PMOS high-end drive circuit, rectifier filter circuit and feedback signal detection circuit. This circuit intelligently adjusts the pressure of the water booster pump, optimizes the proportion of the clean-waste water, improves the amount of water output, saves energy and saves water by collecting and analyzing the feedback signal data.

Key words: PMOS, Water purifier, Data acquisition
