Switch on the power technology development trend

Switching power supply is to use modern power electronic technology, using power semiconductor devices as a switch, through the control switch transistor opened and shut off the time ratio (occupies emptiescompared), adjust the output voltage, maintain stable output of a power supply. In the early 1980 s computer power achieve of switch power supply, the first complete computer power generation, in the 90 s switching power supply has been used in all kinds of electronic, electrical equipment, pabx, communication, electric power test equipment power and control equipment of power supply. booster cable Switching power supply general by pulse width modulation (PWM) control IC and MOSFET composition. Switch power supply, linear power supply and compared, both the cost as the output power increases, power cord but both growth rate each different. Linear power cost in a certain output power point, but higher than the switch power, this is called cost reversal points. Along with the power electronic technology development and innovation, make the switch power technology and constant innovation, the cost is low point to reverse the output power move, and switch power supply provided a broad space for development.
