A phase control circuit is mainly composed of a TRIAC in series with the load resistance, RL, powered by an AC voltage source (in RMS), VAC. A TRIAC may not fire symmetrically on both half cycles. In this condition, derive the average load voltage. Assume the firing delay angles for positive and negative halves are α+ and α-, respectively.
