Buck Converter - Efficiency Factors

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:

    I’ll take fifty percent efficiency to get one hundred percent loyalty.
    Samuel Goldwyn (1882–1974)

    The goal of every culture is to decay through over-civilization; the factors of decadence,—luxury, scepticism, weariness and superstition,—are constant. The civilization of one epoch becomes the manure of the next.
    Cyril Connolly (1903–1974)
