Abstract: MOS is a common power semiconductor devices and has witnessed drastic improvement along with the semiconductor industry and wide application in switching power supply, energy-saving lamps, power conversion and power control. MOS is used as a multi power switching devices in power circuit where conduction resistance is one of the key parameters. As conduction resistance affects the stabil-ity and power consumption of the circuit, its accurate measurement is of great importance. This paper makes a detailed analysis on the resistance of MOS pipe, and introduces several methods to measure the MOS tube conduction resistance.

Key words: MOS tube, conducting resistance, test
