Study Notes
- A diode is an electronic component with two parts: anode and cathode
- The anode allows current flow while the cathode blocks it
- Diodes symbolize their functions with a line for the cathode
- Diodes serve as protection against polarity inversions in circuits
- A diode rectifier consumes a certain voltage (df) during operation
- To power a 3V LED, 3.7V is needed when using a diode rectifier
- Diodes have a specific current limit; use one that can handle more current than the circuit needs.
- In alternating current (AC), diodes let current flow only in one direction
- A bridge rectifier, an arrangement of four diodes, ensures constant polarity regardless of AC input.
- Bridge rectifiers do not produce a perfectly continuous output; further processing with capacitors and regulators is required for smoother output.
- A transformer is needed to connect the rectified output to the power grid.
- A transformer is an electrical device that converts electrical power from one voltage level to another.
- Condensators and regulators are used for voltage regulation and smoothing in the power supply.
