When working on power electronics projects, one common challenge is the need to increase voltage efficiently. This is where the SMPS (Switched-Mode Power Supply) Boost Converter comes in handy. It’s used to step up lower voltages to higher ones, making it perfect for powering devices that require more voltage than your battery or power supply provides.

The Problem :

Imagine you’re building a portable device like a battery-powered LED light or a mobile charging station. Your battery provides 5V, but your circuit needs 12V to function properly. Without the right solution, your device may not work, or worse, could be damaged.

The Solution :

A boost converter helps step up your 5V supply to 12V efficiently, without wasting energy as heat. The process works by rapidly switching the current through an inductor and a capacitor, which increases the voltage. This method is much more efficient compared to traditional linear voltage regulators.

Example :

If you’re building a solar-powered fan that needs 12V to operate but your solar panel only outputs 5V, you can use an SMPS boost converter to step up the 5V to 12V.

Sample Calculation :

Let’s calculate the output voltage for a boost converter using the formula:

Vout​=Vin​×(1+CL​)

Where:

• Vin​ is the input voltage (5V),
• $L$ and C are inductance and capacitance values.

Assuming $L=100\mu H$ and $C=220\mu F$, you can estimate the output voltage required for your application.
