Desirable characteristics of the ideal switch:

It is desirable to have power switches characteristics closer to ideal switch. The ideal switch should have the following characteristics.

  1. Zero resistance when the switch is on and infinite resistance when the switch is off.
  2. Instant switch on and instant switch off.
  3. Infinite current conduction in on state.
  4. Infinite voltage capability when the switch is in off state.
  5. Zero leakage current when the switch is in off state.
  6. Zero voltage drop when the switch is in on state.
  7. 100% efficiency.
  8. Able to control power flow with zero power dissipation.
