Step-down Chopper and its Working Principle

This article outlines the definition, working principle and derivation & formula for average output voltage of a Step-down Chopper. The working principle has been discussed in detail with the help of circuit diagram & output voltage waveform. Definition: A Step-down chopper is a static device that step downs its DC input voltage. The value of … Read more Step-down Chopper and its Working Principle

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

Single Phase Half Wave Controlled Rectifier with RL Load

A single phase half wave controlled rectifier is a thryristor based circuit which produces output voltage for positive half of the supply voltage. However, the phase relationship between the initiation of load current and supply voltage can be controlled by changing firing angle. This is the reason; it is called phase controlled half wave rectifier. … Read more Single Phase Half Wave Controlled Rectifier with RL Load
