Power ElectronicsAC Voltage Controllers

A single-phase AC voltage controller with a resistive load commonly uses two antiparallel SCRs or a?

  • ATRIAC
  • BPower diode only
  • CZener diode
  • DBJT operated as a linear amplifier only
Report an error
Correct Answer: A. TRIAC
Explanation: A TRIAC provides bidirectional controlled conduction and can replace two antiparallel SCRs in many single-phase AC controllers.
Reference: Standard power electronics: ac voltage controllers
