Rectifier:
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC). The process is known as rectification.
Usual rectifiers:
vacuum tube diodes, mercury-arc valves, solid-state diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches.
Rectifier Circuit
Single phase Half Wave Rectifier:
Single phase Full Wave Rectifier
Inverter
A power inverter, or inverter, is an electrical power converter that changes direct current (DC) to alternating current (AC);the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
Capacitor:
A capacitor (originally known as condenser) is a passive two-terminal electrical component used to store energy in an electric field. That is at least two electrical conductors separated by a dielectric (insulator)
Applications of capacitors
- Energy storage
A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.) - Power factor correction
- Suppression and coupling
- Noise filters and snubbers
- Motor starters
- Signal processing
- Sensing
Inductor
An inductor (also choke, coil, or reactor) is a passive two-terminal electrical component that stores energy in its magnetic field.
When the current flowing through an inductor changes, a time-varying magnetic field is created inside the coil, and a voltage is induced, according to Faraday’s law of electromagnetic induction, which by Lenz’s law opposes the change in current that created it.
