Question

Explain the single phase half wave converter drive speed control for dc drive with wave-forms

Answer 1

Answer:

Single Phase Half Wave Controlled Rectifier, as the name suggests, is a rectifier circuit which converts AC input into DC output only for positive half cycle of the AC input supply. The word “controlled” means that, we can change the starting point of load current by controlling the firing angle of SCR.

➢ A Full controlled AC-DC converter is a circuit, which converts an ac voltage into a pulsating dc voltage using both half cycles of the applied ac voltage. It uses diodes of which one half conducts during one half cycle while the other conducts during the other half cycle of the applied ac voltage.
