WebDuty Cycle Effects MOSFET Losses In a power supply circuit, assuming a constant average output power, if the duty cycle is halved, then the current must be doubled. If the duty cycle is reduced to one quarter, then the current must be increased 4x. The product of (I •D) remains constant.
WebFor a rectifier MOSFET (Q2), low R DS(on) is most important, but don’t ignore the gate power. Also, changing the MOSFET R DS(on) changes the duty cycle (D), which effects RMS … WebThe duty cycle of the generated PWM signal is another important consideration as it will decide the active state of the MOSFET. The duty cycle can be calculated as follows – Vout = Vpeak*D. ...
