A rectifier is an electronic circuit or device that converts Alternating current (AC) into Direct current (DC) by allowing current to flow in only one direction, typically using semiconductor components such as diodes or controlled devices like thyristors. It enables AC-powered sources to operate devices that require a stable unidirectional DC voltage. This conversion is […]

P-Channel MOSFETs: Symbol, Construction, Working, Characteristics and Applications
The P-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) is an essential semiconductor device widely used in electronic circuits, particularly in high-side switching and complementary configurations. Like other MOSFETs, it belongs to the family of field-effect transistors (FETs), where current conduction is controlled by an electric field rather than by direct current injection, as in […]
N-Channel MOSFETs: Symbol, Construction, Working, Characteristics and Applications
The N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) is one of the most widely used semiconductor devices in modern electronics, particularly in switching and power applications. It belongs to the family of field-effect transistors (FETs), where the flow of current is controlled by an electric field rather than by charge injection, as seen in […]
12V 5A SMPS: Switched Mode Power Supply Circuit Diagram IC TOP227YN
In this article, you will learn how to design a 12V 5A SMPS circuit that converts 230VAC to regulated 12V DC using the TOP227YN in a flyback configuration. Switched Mode Power Supplies (SMPS) are widely used for high-efficiency AC-to-DC conversion. The flyback topology is especially suitable for low- to medium-power isolated supplies. The TOP227YN is […]
Power Diode: Symbol, Construction, Working, Types and Applications
A power diode is a semiconductor device specifically engineered to conduct large currents and withstand high reverse voltages in power electronic circuits. It is fundamentally a PN junction diode, but its internal structure, doping profile, and packaging are optimized for high-power operation rather than low-level signal processing. In power electronic systems, power diodes play a […]
100-Watt CD4047 Inverter Circuit Construction, Working and Limitations
In this project, we will make a CD4047 Inverter Circuit, and we will also discuss why this type of inverter is not a good or reliable solution for real-world applications. An inverter is an electronic device that converts DC voltage into AC voltage. Inverters play a very important role in power backup systems, especially in […]
