Working of Step Down Chopper – with R and RL Load
A Step-down chopper is basically a high-speed semiconductor switch. The switch can either be a power BJT, power MOSFET, transistor, or SCR depending
Voltage Control of Chopper – Time Ratio & Current Limit Control
A chopper is used to obtain controlled dc output from an unregulated or fixed dc input with minimal power loss. It is a solid-state switching device
Morgan Chopper – Circuit Diagram, Working & Advantages
The Morgan chopper is a single SCR chopper that employs class B commutation or current commutation or resonant pulse commutation. The Morgan chopper
Jones Chopper – Circuit Diagram, Working & Advantages
Jones chopper employs class D commutation to turn off the main thyristor. Here, a charged capacitor is switched by the auxiliary thyristor in order to
Voltage Control Methods of Inverter – PWM Technique
Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, External Control of AC Output Voltage,
Deadlock Prevention in Operating System (OS)
Deadlock prevention means placing restrictions on resource requests so that deadlock cannot occur. Deadlock can be prevented by denying at least any
Difference Between Half Controlled (Semi) & Fully Controlled Converter
Using a half-controlled converter a positive dc output voltage with unidirectional current is obtained. Whereas in the case of fully-controlled
