In this tutorial, you will learn, how to design Boost converter proteus simulation.
As you know that, Boost converter is a power electronics converter, it converts low voltage into hight voltage. The Boost or step-up converter, is a configuration that converts a voltage output which is above the input voltage. In other words, Boost converter boost the input voltage to a high voltage.
This is a circuit diagram of Boost converter. It consists of an inductor, diode, capacitor and a switching device.
With the shown component values, the converter works by ensuring a continuous current through the inductor (IL), for this reason it's known as a continuous mode.
By reducing the inductor value, the converter will move in the discontinuous mode.
The voltage output can be calculated by this formula
Vout = Vin * T/(T-T1) where:
Where T = PWM period
And, T 1 = OFF time.
In the example for T=20us and T1=15us, output voltage will be about 16 volts.
We use MOSFET as a switching device.
To provide, Pulse width modulation signal to MOSFET, we used a P W M generator signal of proteus,
Now place all components in proteus window and make connection according to this circuit diagram.
Now open, PWM signal, and make setting according to these values.
After that connect output voltage probe and output current probe.
Now add analog graphs to check waveforms of output current and voltage.
In order to check output voltage waveform, right click on graph, and make starting and end time settings.
After that simulate the graph.
As you can see from the graph, output voltage first shoots up and after some time settles to 16 volts output.
Not that, while designing boost converter practically, we can remove these starting output voltage fluctuations by using a PID controller.
After that, follow the same procedure to see output current waveform.
As you can see, output current is continuous.
This is how we can simulate boost converter in proteus.
