Constant current generators (CCGs), as the name suggests, are circuits designed to produce a steady load current regardless of significant fluctuations in load resistance or voltage levels. Basic Constant Current Generator Circuit Illustrated in Figure 1 is a basic example of such a circuit. In this configuration, Q1 operates in the common emitter mode. A […]

Understanding Triac Snubber Network Calculations
You may find electronic circuits that frequently utilize triacs to manage mains powered loads. However, these setups commonly feature an inconspicuous capacitor and resistor combination across the triac – a snubber network. The functions of these components are more intricate than they seem. Exploring snubbers and grasping basic triac theory is valuable. Triac Operation A […]
How Load Conducts in Half-Bridge Driver Circuits like IR2184 or IR2110
Many folks, especially beginners, they get fully confused when they try to use a half-bridge driver circuits using ICs like IR2184 or IR2110. They look at the datasheet diagram and start thinking, “Bro, how the load will conduct? The MOSFETs are switching one by one so how the current will pass through the load? Looks […]
How To Use Triac For AC Power Control
Here we are talking about controlling things like lamps, motors, heaters, and other similar electrical loads. The devices we use for this purpose are called thyristor and triac, OK? Both these devices, thyristor and triac, they can actually do this job like simple switch ON/OFF or they can also adjust the power given to these […]
SCR/Thyristor Circuit Configurations
Now in this article we will try to understand step by step how we can use this thyristor in practical work. That can be for controlling heavy loads like electric lamps, heaters, or motors and so on. So this part is more about real application and not only about theory. How We Trigger The Thyristor […]
Understanding Bipolar Junction Transistors (BJTs)
If we look at the diodes, their internal construction look very simple. They are made by joining two pieces of semiconductor material, and this is called a pn-junction. But when we talk about bipolar junction transistor or bjt, then things get little more complicated. It needs adding one more layer of semiconductor material, and that […]
