MPPT

Perturb and Observe MPPT | What matters the most ??

The perturb and observe MPPT can track the power fast if the step increment (Delta V in Fig. 1) in the operating point is increased. Although, it will enhance the dynamic response of the MPPT but it will also increase the power oscillations around the MPP. To solve this issue of power oscillations, the step size in each perturbation can be reduced at...

Leakage Inductance

Ways to minimize leakage inductance of flyback transformer

For a flyback inverter one of the design task is to keep the leakage inductance as low as possible. While there are limitations when it comes to the reduction of leakage inductance there exist methods to solve this issue. It must be kept in mind that the low leakage inductance is very much essential for efficient energy transfer to the output. Let us...

Vision 2025: Renewable Energy mix of Pakistan

To fathom these energy-mix bar charts shared on the web (predicting contradicting figures, defying logic, and no circumstantial evidence) is prodigal. This article is written for plain people of Pakistan. A normal citizen demands uninterrupted electricity with no cuts. That is it. For now, we have seen that the futile scheme to repudiate Circular Debt and improve energy deficiency seems to have failed....

Decoupling capacitor

Decoupling capacitor | What's the requirement ?

Microinverters for single phase grid connections have an inherited issue which is commonly known as double line frequency problem. The problem is about the power pulsations of the AC grid which is double the line frequency. This power is time varying in nature while the power output from the PV module is constant (MPPT is used ). This is shown in Fig.1. This...
