PWM (Pulse Width Modulation) can be easily generated in MATLAB using simple MATLAB functions. We have already discussed PWM generator circuit using 741 Op-amp in previous posts. In PWM, the width of the pulses is varied according to the amplitude of the AF message signal. PWM is basically an analog pulse modulation technique. It does modulation of the duty cycle of the … [Read more...] about Code for Pwm (Pulse Width Modulation) Generation in Matlab
We may come across many circumstances where we need 12V from a 5V (as from USB ports which only provide 5V), but it may not be sufficient to drive all the circuits. To face such situations we are introducing a dc to dc boost converter circuit which can generate 12 volt from 5 volt. Today boost converter applications are used in different devices like dc dc … [Read more...] about How to Make a Simple Boost Converter with 555 Timer?

You can use this best battery charger circuit as car battery chargers, Inverter battery chargers, Emergency light battery chargers, etc. An automatic indicator alarm circuit also comes along with this battery charger schematic. The main advantage of this indicator is that a buzzer informs us when the battery needs … [Read more...] about Simple Battery Charger Circuit and Battery Level Indicator With Low Battery Recharge Alarm
An electrical cut sheet is a sheet that provides information on the electrical equipment you are buying. It carries information such as sizes, ratings, capacities, colors, and other information required for a perfect installation. Electrical cut sheets also provide you with alternate model numbers and features. These are particularly helpful when you want to compare products … [Read more...] about What is an Electrical Cut Sheet
A homeowner can replace an electrical panel by himself, given that the building codes permit him to do so. However, he ought to have proper knowledge and experience. With or without the experience, the best course of action is to hire a professional electrician to handle the work.
