In this post I have explained about MOSFET bidirectional power switches, which can be used for operating a load across two points bidirectionally. This is simply done by connecting two N-channel, or P-channel MOSFETs back to back in series with the specified voltage line. What is a Bidirectional Switch A bidirectional power switch (BPS) is […]

How to Calculate Ferrite Core Transformers
Calculating ferrite transformer is a process in which engineers evaluate the various winding specifications, and core dimension of the transformer, using ferrite as the core material. This helps them to create a perfectly optimized transformer for a given application. The post presents a detailed explanation regarding how to calculate and design customized ferrite core transformers. […]
BJT Transfer Characteristics
In BJTs or bipolar transistors, transfer characteristics can be understood as plotting of an output current against an input-controlling magnitude, which consequently exhibits a direct “transfer” of variables from input to output in the curve represented in the graph. We know that for a bipolar junction transistor (BJT), the output collector current IC and the […]
5 Best 40 Watt Amplifier Circuits Explored
In this post I will talk about 5 outstanding, easy to build, low distortion Hi-Fi 40 watt amplifier circuits that can be further upgraded to higher wattage through some minor tweaks. This article was contributed to me through email by a dedicated follower Although you may find several hybrid output modules available, hardly any of […]
H-Bridge Bootstrapping
Bootstrapping is a crucial aspect that you will find in all H-bridge or full bridge networks with N-channel mosfets. It is a process in which the gate/source terminals of the high side mosfets are switched with a voltage that’s at least 10V higher than its drain voltage. Meaning, if the drain voltage is 100V, then […]
1000 watt to 2000 watt Power Amplifier Circuit Diagram
In this article I will elaborately discuss a simple to built yet awesome 1000 watt amplifier circuit, which could be easily upgraded to achieve upto 2000 watt output. It uses relatively fewer components and could be quickly set up for getting a massive 1000 watt power output on any 4 ohm, 1kva loudspeaker. This circuit […]
