Definition: The word 'static' corresponds to something which undergoes no change or is fixed and a 'switch' is used for the purpose of making or breaking a connection in an electric circuit. The static switch is a device which executes switching operation without the presence of moving parts. Generally, the power semiconductor devices that hold the ability to get turned ON or OFF within a fraction of microseconds, find application as fast-acting static switches. In low power applications, … [Read more...] about Static Switch

Power electronic converters are classified into four major categories. Out of the four major categories, two are further classified. A power electronic system may have one or more power electronic converters. Here in this content, we will discuss each type of power converter in brief. The power semiconductor devices that constitute the power converter exhibit switching characteristics to shape the input power of one form to an output power of some other form. Introduction Power Converters … [Read more...] about Types of Power Electronic Converters

Basically, in power electronics, solid-state electronics, is used that performs the action of control and convert of the electric power. Power Electronics is regarded as an important subfield of electrical and electronics engineering. The pictorial representation given below provides an idea about the … [Read more...] about Power Electronics

Definition: The type of filters that are designed to block or highly attenuate a specific band of frequencies is known band stop filter. It is sometimes known as band reject or band eliminate filter. A more common name for these filters is Notch Filter. It is a second-order filter that has two cut-off frequencies. Band reject filters are formed by utilizing the characteristics of high pass and low pass filters. What are Filters in Electronics? Filters serve as crucial components of the … [Read more...] about Band Stop Filter

Phase Difference is defined as the delay between two or more alternating quantities while attaining the maxima or zero-crossings giving rise to the difference in their phases. This difference in two waves is measured in degrees or radians and is also known as phase shift. It is sometimes defined as the difference between two or more sinusoidal waveforms in consideration with a reference axis. It is denoted by φ and corresponds to the shift in the waveform along the horizontal axis from a … [Read more...] about Phase Difference in AC Circuits

Solid State Relay also known as Solid State Switch is an electronic device used for switching the load on and off when the external supply voltage is provided across the input terminals of the device. It is abbreviated as SSR. These are basically semiconductor devices used to control the load thus these devices use electrical properties of solid-state semiconductors like transistors, MOSFET, TRIAC, etc. to execute input and output switching operations. What are Relays? Relay is basically a … [Read more...] about Solid State Relay (SSR)

Definition: Freewheeling diode is used to protect the circuit from unusual damage caused due to abrupt reduction in the current flowing through the circuit. It is also known as Flyback diode and forms connection across the inductor to remove Flyback voltage generated across it. Freewheeling diodes are also known as kickback diode, clamp diodes, commutating diodes, suppression diodes, or snubber diode etc. Here in this article, we will discuss the factors responsible for the need of such … [Read more...] about Freewheeling (Flyback) Diode

Definition: Phase-locked loops are the circuits used to maintain synchronization between input and output frequency of oscillator circuits by comparing the difference in phase of the two signals. With the evolution of IC, it has emerged as the basic building block of electronic circuits. Phase-locked loops are abbreviated as PLL and are basically a feedback circuit comprising of a phase detector (or comparator), a low pass filter and voltage-controlled oscillator along with an … [Read more...] about Phase-Locked Loops (PLL)

Definition: Beat Frequency Oscillator or BFO is an oscillator that produces a sinusoidal signal of the variable audio frequency range. It provides such a frequency that can be varied over a very large range. BFO was invented in 1901 by Reginald Fessenden. It is among the most common type of oscillator that can generate a signal of variable frequency at its output. Block Diagram and Working of Beat Frequency Oscillator The figure below represents the block diagram of a BFO:Here as we can see … [Read more...] about Beat Frequency Oscillator (BFO)

Definition: Phase shift oscillators are the oscillators that generate a stable sinusoidal signal at the output. Basically, the circuit has, an amplifier unit like transistor or op-amp along with a feedback network comprising of resistors and capacitors. Thus, is also known as RC phase shift oscillator. The RC network is present in the feedback path is connected in ladder fashion thus also known as ladder RC phase shift oscillator. We know for an RC circuit; the output voltage leads the input … [Read more...] about Phase Shift Oscillator
