WebSimply defined, rectification is the conversion of alternating current (AC) to direct current (DC). This involves a device that only allows one-way flow of electric charge. As we have seen, this is exactly what a semiconductor diode does. The simplest kind of rectifier circuit is the half-wave rectifier. Webseries ac motor has the same general characteristics as the series dc motor, a series motor has been designed that This ac/dc motor is called a universal motor. Universal motors operate at lower efficiency than either the ac or dc series motor. Universal motors do not operate on polyphase ac power. Q2. Q3.
