Hey Guys! Welcome you onboard. Today, I'll discuss an important topic titled "Introduction to PWM" . I will try to cover everything related to PWM i.e. PWM Definition, PWM generation, why we need PWM signals? how it is used in a variety of applications ranging from motors, heating systems, hydraulics, control valves, pumps etc. One important thing to mention here is "PWM can be applied on both AC and DC electrical signals". So, let's get started: What is PWM (Pulse Width Modulation)? As we all know, there are two main types of electrical signals i.e. AC and DC. Both of these signals are used as a power source for different types of electrical appliances. Now if we have a look at these electrical appliances, they operate at different voltage levels and may also need variable voltage supply( ...

No. Inverter tutorial series 1 Basics of Inverters with Topology 2 Major Components of Inverters 3 Pure Sine Wave Inverter Design with Code 4 Modified Sine Wave Inverter Design with Code Hello friends, I hope you are doing well. This is the first tutorial in our inverter series. We will begin with the purpose of an inverter, study the common output waveforms and then compare the power-stage topologies used to produce AC from a DC source. An inverter looks simple in a block diagram, but a useful design must control voltage, frequency, waveform quality, current, temperature and fault energy at the same time. A circuit that produces an alternating voltage on an oscilloscope is not automatically a safe or well-regulated AC power source. Our goal here is to understand the engineering decisions ...
