Difference between Step-up and Step-down Chopper

The main difference between a step-up and step-down chopper is that average value of output voltage of former is greater than its input DC voltage whereas it is less than the DC input voltage for latter. This is the basic but major functional difference between the two. Step-down and step-up choppers are static devices which … Read more Difference between Step-up and Step-down Chopper

Step-up Chopper – Definition and Working Principle

Definition: Step-up chopper is a static device whose average output DC voltage is greater than its input DC voltage. It is different from the step-down chopper. In step-down chopper, the average value of output voltage stepped down i.e. it is less than its input voltage. Working Principle of Step-up Chopper: To understand the working principle, … Read more Step-up Chopper – Definition and Working Principle

Complex Power – Definition, Explanation & Significance

Definition: Complex Power is basically the representation of electrical power in the form of complex number. Like a complex number, it consists of real and imaginary part. Real part represents the active power whereas the imaginary part represents the reactive power. It is generally represented by symbol S. If active and reactive power be P … Read more Complex Power – Definition, Explanation & Significance

Unilateral and Bilateral Elements

Unilateral and Bilateral Elements are the two different types of electrical / electronic circuit element on the basis of their V-I characteristics on reversal of voltage polarity. This article describes Unilateral and Bilateral Elements and circuit in detail with relevant diagrams. Unilateral Elements: Unilateral elements in electrical circuit is defined as the element whose V-I … Read more Unilateral and Bilateral Elements

Impedance Triangle

Definition: Impedance Triangle is a right angled triangle whose base, perpendicular and hypotenuse represents Resistance, Reactance and Impedance respectively. It is basically a geometrical representation of circuit impedance. Explanation of Impedance Triangle: Impedance consists of two components viz. resistance and reactance. Therefore, it can be expressed in these two components. Let the impedance of an … Read more Impedance Triangle

What are Reactance and Impedance in Alternating Current Circuit?

Reactance is defined an electrical quantity due to which alternating current is opposed by inductor or capacitor or combination of both of them in a circuit. Impedance is the net opposing factor to alternating current. Reactance may also be called impedance offered either by inductor or capacitor. Reactance is denoted by X and impedance by … Read more What are Reactance and Impedance in Alternating Current Circuit?
