Switch power supply

Switching power supply is to use modern power electronic technology, www.siliconray.com control switch tube opened and shut off the time ratio, maintain the stable output voltage of a power supply, switching power supply general by pulse width modulation (PWM) control IC and MOSFET composition. Switch power supply, linear power supply and compared to the cost of both as the output power increases, 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, making the switch power technology is in constant innovation, the cost low output growing point to reverse the power move, the switch power supply provided a broad space for development
