Types of Power Amplifier Classes Explained in Simple Words
In this post I am going to explain power amplifiers and their classification according to their output electrical characters and application. We will be exploring amplifier classes: A, B, AB, C, D, E, F, G, H, I, S and T briefly and yes, that’s a lot of amplifier types that are available in today’s electrical […]
Simple Triac Triggering Circuits Explained
In this post I have explained the fundamental methods of triggering a triac, and also discuss the right way to connect the terminals of a triac. Triacs are solid-state bidirectional thyristors that can switch across both the AC half cycles on a 120-volt or 240-volt Ac power system. A triac could be activated (switched on and […]
How to Calculate Heatsinks
Heatsinking is critical for power devices in circuits that are intended to maximize their performance. When heat from the power devices cannot be moved away very quickly, the power devices and its operating elements could be damaged. You may calculate how hot your semiconductors could become while operating, using a couple of easy formulas. Using formulas gets rid of guesswork and […]
Police/Ambulance Siren Circuit with Rotating Beacon Light
In this post I have explained how to construct a police, ambulance or a fire truck siren circuit using evergreen IC 555 timer and we will also learn how to build a revolving beacon light without any mechanical parts. The proposed project is divided into two parts the siren circuit and the rotating beacon light, […]
3 LED Battery Level Indicator Circuit
The proposed 3 LED battery level indicator can be typically used for monitoring a 12 V lead acid battery charge level, through 3 distinct LED illumination. The entire circuit is built using just a couple of BJTs , a few zener diodes, resistors and LEDs. Different Ways to Check Battery Voltage A hydrometer is perhaps […]
