Definitions

  • Each of these DC-DC converter types is suitable per se for use as a switch mode power supply, and are indeed widely used in, for example, supply units and drives for tools and domestic appliances, supplies for lighting equipment, and the like.
  • snubbers for bipolar transistors as a means of reducing switching losses and counteracting interference signals.
  • the combined use of a self-inductance, diode, resistor, and capacitor is necessary for practical snubbers if they are to be effective in switching both to the conducting and to the non-conducting state.
