A Zener diode allows current in the forward direction like a regular diode
but also conducts in reverse when the voltage exceeds a specific Zener breakdown voltage (Zener voltage).
Common Zener diodes: 500mW BZX55 and 1.3W BZX85, like BZX55C7V5 (7.5V).
Zener diodes can be series-connected with silicon diodes for various reference voltages.
• Rectified voltage from rectifier has high ripple content.
Desired output is a pure, ripple-free DC waveform.
Filters are used to remove ripples.
Types of filters: capacitor filter, LC filter, choke input filter, ㅠ type filter.
A regulated power supply converts AC to a stable DC output, ensuring consistency despite input fluctuations. Also called a linear power supply, it consists of various circuit blocks to maintain a constant DC output from an AC input.
The Uni-junction Transistor (UJT) is a solid-state, three-terminal device.UJT is constructed using P-type and N-type semiconductor materials. It has a single PN-junction formed within the main N-type channel.
The transistor consists of three layers: NPN or PNP. The collector current (Ic) is dependent on the base current (IB). A change in base current IB results in an amplified change in collector current Ic. The ratio of these currents ranges from 15 to 100 and called beta ẞ.
