The Problem :

When working with SMPS (Switched-Mode Power Supplies), one common challenge is dealing with Power Factor Correction (PFC). A poor power factor can lead to inefficiency, waste of energy, and overheating in circuits, which can affect the performance and longevity of your designs. In simple terms, a low power factor means that the current is not being used efficiently, leading to wasted energy and more stress on your components.

The Solution :

To fix this, you can integrate a PFC circuit into your SMPS design. The PFC circuit works by shaping the input current to match the input voltage waveform, improving the power factor and making the system more energy-efficient.

Practical Example :

Imagine you’re designing an SMPS to power a motor in a fan. Without a PFC circuit, the current may not be synchronized with the voltage, causing inefficiency. With the PFC circuit, the current will be adjusted to match the voltage, reducing energy loss and making the motor run smoother and cooler.

Sample Calculation :

Let’s say your SMPS draws 1.5A of current at 230V.

The input power is calculated as:

Power = Voltage x Current = 230V x 1.5A = 345W.

If the power factor is 0.7, the effective power used is :

Effective Power = 345W x 0.7 = 241.5W.

With a PFC circuit, the power factor can improve to 0.95, reducing the wasted energy.
