🔍 Key Concepts

• Identify whether the rectifier section (T1, D1, D2) is half-wave or full-wave based on the transformer and diode arrangement. • Relate input line frequency to ripple frequency for different rectifier types (half-wave vs full-wave). • Consider how many DC pulses occur for each cycle of the AC input in this specific circuit.

💭 Think About

• Look closely at the secondary of T1 and how D1 and D2 are connected. Does this configuration conduct on both halves of the AC cycle or only one? • If the rectifier conducts on both halves of the AC wave, how does that change the number of ripple peaks per second compared with the 60 Hz input? • How does the presence of filter components (L1, C1) affect the shape of the output versus the frequency of the ripple? Does it change the ripple frequency or mainly the amplitude?

✅ Before You Answer

• Confirm whether the circuit is a center-tapped full-wave rectifier or a single-diode half-wave rectifier. • Count how many rectified peaks appear in one 1/60-second interval at the rectifier output for this configuration. • Verify that filtering components like inductors and capacitors do not change the ripple frequency produced by the rectifier itself, only its magnitude.
