So this circuit changes 12V DC power from a battery into 115V AC power at 60Hz, 230V 50Hz, depending on the transformer secondary specifications. It can drive small AC electrical items up to 100 watts total power. It uses two UJT transistors to make the 60Hz timing speed and two power SCRs or transistors to […]

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 […]
Understanding CMOS IC 4035 Datasheet – 4-Bit Parallel In Parallel Out Shift Register
So now we are talking about this digital IC called 4035 which is made using CMOS technology, that means it will use very low current and will give us high noise immunity. Inside this IC we have got 4 flip-flops which are arranged in such a way that they can hold and shift 4-bit data. […]
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 […]
Understanding AC Circuit and Calculating AC Waveform
The sinusoidal waveform or sine wave is the most commonly used AC waveform in circuit theory. When a periodic AC waveform is produced by a voltage source, it creates an EMF that changes polarity at regular intervals, with the time it takes to complete one full reversal known as the waveform’s period. Direct current, also […]
Understanding MOSFET Current Rating in Datasheets
In this post I will comprehensively explain the current rating of MOSFETs in their datasheets, and helps us to understand how it is calculated by the design engineers, keeping in mind the various external parameters, which potentially impact the current limitations of the device. In simple terms, MOSFET current rating can be defined as the […]
