Boost Converter using MOSFET IRFZ44N in Proteus

Hello Learner! Welcome to another exciting experiment at The Engineering Projects. We hope you are having a great day. In this lecture, we'll seek information about the Boost Converter Circuit from scratch to result in quick and easy steps. So, if you don't know about the experiment then don't worry because every Expert was once a Beginner. We'll talk about the following topics:

1. What is IRFZ44N MOSFET Boost Converter?
2. What is the brief introduction of components of circuit?
3. How can we implement the IRFZ44N MOSFET to design circuit of Boost Converter?

You will know some useful information about the topic in the DID YOU KNOW sections.

IRFZ44N MOSFET Boost Converter

During the experimentation of electronic circuits, we often face the situation when we have to amplify the voltage signals or voltage power. For example, when we need the 12V in the experiment but we have just 9V battery or any such case. There are many ways to tackle such condition but it requires a lot of energy and steps. But when we search our solution in the world of Switched Mode  DC-DC Converters, we find a very easy and simple solution of our problem in the form of IRFZ44N MOSFET Boost Converter. NOTE: One can make the BOOST Converter using one of many MOSFETs but we have focus on IRFZ44N due to its best result. Prior to start the experiment, it is compulsory to have some basic information about the circuit. We define the IRFZ44N MOSFET Boost Converter as:

The Boost Converter is the Electronic device that uses a MOSFET (IRFZ44N MOSFET in our case) to convert it's Low input DC Power into High output DC power.

The IRFZ44N MOSFET Boost Converter is a switched-mode power supply and this is consist of at least two semi-conductor device and minimum one energy storage element.

DID YOU KNOW????????????????

We call IRFZ44N MOSFET Boost Converter as Switched Mode Devices because basically, they are the semi-conductor Switches that turns their condition On and Off very rapidly.

Components of IRFZ44N MOSFET Boost Converter

Throughout the experiment, we'll use the components that will convert the low level Voltages into High Level Voltages. A brief introduction of the components is given next:

IRFZ44N MOSFET

The IRFZ44N Metal Oxide Semi-Conductor Field Effect Transistor is used as a switch in the IRFZ44N MOSFET Boost Converter. The main reason behind this is one can change its conductivity by changing its Gate Voltage and hence we can use it as a switch. This is one of the key procedure to amplify the voltages in the IRFZ44N MOSFET Boost Converter.

Inductor

We all know an inductor is a passive two- terminal magnetic storage device that stores the energy due to its coiled shape. Due to its storage capability, it resists the sudden change of current in the IRFZ44N MOSFET Boost Converter. In this way, it work as a stabilizer in the circuit and play an important role.

Diode

A diode is a reverse biased component of the IRFZ44N MOSFET Boost Converter. It is designed in such a way that it allow the flow of current only in one direction. Hence, in the IRFZ44N MOSFET Boost Converter the Diode allow the flow of current from inductor to the capacitor in only in the condition when it is forward biased.

Capacitor

A capacitor is a device that stores the energy in the form of charges. In IRFZ44N MOSFET Boost Converter when the Switch is turned off, the diode does not allow the flow of current through the capacitor. This is the condition when the stores energy in the form of charges from capacitor is used and the capacitor then works as the source of energy in IRFZ44N MOSFET Boost Converter.

Output graph

Before this we saw the components that we'll use in the formation of circuit, but we require other components as well to examine the result and working. We examine the result through an output device that shows us the result in the form of graph. For our experiment, we'll use analogue analysis graph for the output.
