50A High Current Sensor IC ACS758: Circuit Diagram
So in this post we will try to understand everything about ACS758 current sensor, how this works, how we can use it, what is the technical specs, what is inside this IC and how to use in real circuits etc. This ACS758 is actually made by Allegro Microsystems and this is a very strong and […]
Explained: Snubber Circuit for MOSFET H-Bridge
Here we are going to talk deeply about snubber circuits and why we must use them with MOSFET H-bridge circuits. Because if we do not put snubber in H-bridge then that MOSFETs might blow off during switching. Specially when we drive inductive loads like transformer, motor, relay, solenoid, etc. then this thing becomes very serious. […]
Do We Need a Freewheeling Diode Across the Inductor in Boost Converter?
So here we are trying to understand whether we must put a freewheeling diode directly across the inductor in a boost converter or not, to safeguard the switching transistor? How Boost Converter Works So in a boost converter, we got one inductor, one power switch like a MOSFET, one diode and one output capacitor. Input […]
SG 3525 Automatic PWM Voltage Regulation Circuit
In this post I have explained a simple configuration which can be added with all SG 3525/3524 inverter circuits for implementing automatic PWM output voltage regulation by the IC. The solution was requested by Mr. Felix Anthony. The Circuit Problem: Sir, I would need your help on a project about a schematic that I do […]
USB 5V To 24V DC to DC Boost Power Regulator Module
This is a USB 5V to 24V Adjustable Boost Converter Module and it helps us step up a lower voltage into a higher voltage which we can adjust as needed. Now let us go through everything in detail step by step. Inputs – Where We Give Power Now we got three ways to power this […]
