Three Phase Motor Drive Using Space Vector Pulse Width Modulation Technique

Three Phase Motor Drive Using Space Vector Pulse Width Modulation Technique (SVPWM): The space vector pulse width modulation is a technique, which is used for driving the motor at different frequencies. In recent years, different pulse width modulation techniques are used for driving the ac motors, such as sine wave pulse width modulating (SPWM), unipolar pulse width modulation (UPWM). In these techniques, ...

Bode Analyzer using STM32F407 Discovery board

Introduction Frequency domain analysis is very important to know more about any system/ circuit or transfer function that we deal with. And the first thought comes to our mind about frequency domain analysis is "Bode plot". Bode plot is a combination plot of magnitude and phase difference of output vs. input of a cosine wave of single frequency, when it is applied to a circuit. Each of these cosine wave (si ...

Printed circuit board manufacturer – JLCPCB Review

Recently, I had the opportunity to test the printed circuit boards (PCB) offered by JLCPCB. These tests were made in two different boards of the brand and here I’ll report my impressions about them. Due to the spread of the maker culture and the do-it-yourself (DIY) and easy access to components and a huge amount of technical information available on Internet, it has become much simpler to develop a solutio ...

Lab 2: Basic digital input and output

Description Today we will learn how to read digital inputs from a push button switch. A digital input has only two values: 1 and 0. The configuration of the push button switch is same as that of the reset switch except it goes to a different port pin. The status of the switch will be read through RC1 and every time when it is pressed, an LED connected to RC0 will be toggled ON and OFF. Required Theory You m ...

How To Use PIC Microcontroller For Voice Input And Output

Microcontrollers are purely digital devices which work on logic0 and logic1 voltages; still they are widely used for analog signal processing. There are specialized signal processors chips available which are custom made for particular applications; however a general purpose microcontroller is more than enough for small kind of signal processing applications like audio signal input and output. The microcont ...
