Its best initial attraction is the low system , simplicity and cost ease of implementation . For low current output and power level below 50W, DCM flyback is the operating modepopular .
Webfeetwet. 2,322 9 30 55. 2. "Flyback" is a play on words, the same as "bootstrap" is for amplifiers and software. It is a way of feeding some of the output back to an input stage to boost performance. The term originated in the 1950's with the HV flyback transformer for the picture tube. Webmakes QR Flyback efficiency higher specially high line/lighter loads compare to a FF Flyback 2. Less Conducted EMI: Due to the ripple voltage appearing across the bulk capacitor, the switching frequency is modulated of QR Flyback is modulated at twice the mains frequency. This causes the spectrum to be spread over the wide frequency band …
WebThe flyback converter design is very simple and contains electrical components like a flyback transformer, switch, rectifier, filter, and a control device to drive the switch and achieve regulation. The switch is used to ON and OFF the primary circuit, which can magnetize or demagnetize the transformer. The PWM signal from the controller ... http://bbs.eeworld.com.cn/thread-1181493-1-1.html
