- 2. Rectification Basic Definition: Rectification is the conversion of an alternating current (AC) to a direct current (DC). This is done by using a device that allows only a one-way current, like a diode.
- 3. Kinds of Rectification 1. Half-wave II. Full-wave
- 4. I. Half-Wave Half-wave rectification is a simpler and easier way of converting your AC to DC. It is called a half-way circuit, because you only allow half of the AC cycle to pass, thus having only used half its capacity.
- 5. Recall:
- 8. II. Full-wave A more common and efficient approach to convert AC current to DC current is by manipulating the AC wave such that all of it is used.
- 11. Polyphase full-wave bridge design -When polyphase AC is rectified, the phase-shifted pulses overlap each other to produce a DC output that is much “smoother”
- 12. Summary Half-wave rectifier Uses only positive part of the sine graph Easier to make but more inefficient Full-wave rectifier Uses all parts of the sine graph(converts the negative to positive) More efficient, more commonly used
- 13. Filter A filter is an AC circuit that separates some frequencies from others within mixed-frequency signals. Audio equalizers and crossover networks are two well-known applications of filter circuits.
- 14. Low-pass a low-pass filter is a circuit offering easy passage to low-frequency signals and difficult passage to high- frequency signals 2 Kinds: 1. Inductive low-pass 2. Capacitive low-pass
- 17. High-pass A high-pass filter's task is just the opposite of a low-pass filter: to offer easy passage of a high-frequency signal and difficult passage to a low- frequency signal. 2 Kinds 1. Inductive high-pass 2. Capacitive high-pass
- 20. Summary Low-pass High Low
