Description

PCB design (Kicad) to test the DPP architecture used in MPPT designs

README

DPP Architecture Test v1.0

This PCB was designed to test the DPP architecture used in MPPT designs. The software used to designed the PCB is Kicad 6.

The tests performed with this PCB will contribute to develop the project MultiMPPT, that is a low cost high efficiency MPPT with multiple inputs. For more information about the project check the following link.

Hardware Design

The following image contains the schematic of the PCB:

Where:

• J1, J2 and J3 are used to connect the solar panel and connect to other components inside the MPPT (during the tests).
• T1, C1, C4, Q1, R1 and R2 are the main components of the Flyback Converter.
• D1, D2 and C3 create a snubber circuit to protect Q1. There will be used D2 + C3 or D1.
• U1 and C2 is a gate driver to facilitate the change of state of Q1 at high frequencies (controlled using a microncontroller connected to the board).
• J3 is a connector to give access to the gate driver.
