TVS diodes protect circuits from voltage spikes. Let's discover what they are and what makes them special!
Building a voltage source for small circuits with a zener diode? Let's explore how this is possible, let's build a shunt regulator.
Today, we are going to build a low voltage alarm using a zener diode and an LM393 comparator.
What can we use zener diodes for? This time, we look at their use as voltage references.
The zener effect is the dominant breakdown effect in low voltage zener diodes. Let's take some time to learn more about it.
It is a special type of diode designed to operate reverse biased: the zener diode.
They are a very effective protection against over voltage and reverse polarity. Let's look at how diodes can be used as input protection.
It is a necessary component in many circuits with inductive loads: the flyback diode.
It is used in many products and is de facto the standard rectifier: the full-wave bridge rectifier. Let's discover how it works.
A popular application for diodes are rectifier circuits. Today, we are going to look at a simple half-wave rectifier.
Let's look back at what we learned in this project series and talk about which solution fits which use case.
Last time we built an AC source using a transistor H-bridge. This time, we replace the transistors with MOSFETs to improve the efficiency.
We built ourselves a working, but quite complex AC source. However, our solution is not the only possible one.
In the last part of this project, we used an op amp to increase the current. This time we are going to increase the output voltage.
After we learned about different ways to generate a sine wave, it is now time to speak about amplifying the output signal.
Today, we are going to look at a third method for generating a sine wave with an Arduino: using the Arduino's PWM output as DAC.
We already created a sine wave using a DAC. Today, we are going to try out another method: transforming a square wave into a sine wave.
Let's move on and generate a sine wave signal for our AC source. Our first approach: using a DAC.
