Efficiency Factors
Conduction losses that depend on load:
- Resistance when the transistor or MOSFET switch is conducting.
- Diode forward voltage drop (usually 0.7 V or 0.4 V for schottky diode)
- Inductor winding resistance
- Capacitor equivalent series resistance
Switching losses:
- Voltage-Ampere overlap loss
- Frequencyswitch*CV2 loss
- Reverse latence loss
- Losses due driving MOSFET gate and controller consumption.
- Transistor leakage current losses, and controller standby consumption.

Famous quotes containing the words efficiency and/or factors:
““Never hug and kiss your children! Mother love may make your children’s infancy unhappy and prevent them from pursuing a career or getting married!” That’s total hogwash, of course. But it shows on extreme example of what state-of-the-art “scientific” parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.”
—Lawrence Kutner (20th century)
“I always knew I wanted to be somebody. I think that’s where it begins. People decide, “I want to be somebody. I want to make a contribution. I want to leave my mark here.” Then different factors contribute to how you will do that.”
—Faith Ringgold (b. 1934)
