Voltage Boost Converter Proteus Simulation

Introduction: Voltage Boost Converter Proteus Simulation.
The Boost converter is a power electronics converter, it converts low voltage into high voltage. The Boost or step-up converter is a configuration that converts a voltage output, which is above the input voltage. In other words, the Boost converter boosts the input voltage to a high voltage.
Proteus Circuit Diagram:
This is a circuit diagram of a Boost converter. It consists of an inductor, diode, capacitor, and a switching device. You can refer to any power electronics textbook for its working. With the shown component values, the converter works by ensuring a continuous current through the inductor, 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 is the PWM period And, T 1 is an OFF time of PWM.
For this example, we will convert 4 volts input, into 12 volts output. That means we need a 75 % duty cycle. If we put T = to 20 microseconds, and T1 = to 15 microseconds in this formula, the output voltage will be about 12 volts. In other words, if we provide a 75% duty cycle to MOSFET, the output voltage will be about 12 volts. We use MOSFET as a switching device.

Proteus Simulation Steps:
1. To provide, Pulse width modulation signal to MOSFET, we used a PWM generator signal of proteus,
2. Now place all components in the proteus window, and make a connection according to this circuit diagram.
3. Now open, PWM signal, and make setting according to these values.
4. After that connect the output voltage probe and output current probe.
5. Now add analog graphs, to check waveforms of output current and voltage.
6. In order to check output voltage waveform, right-click on the graph, and make starting and end time settings.
7. After that simulate the voltage.
8. As you can see from the Voltage, output voltage first shoots up, and after some time settles to 12 volts output.
