Maximum power point tracking IC
12.2.2 MPPTCore module
This module contains the Maximum PowerPoint Tracking (MPPT) algorithm. This
algorithm continuously tracks the maximum power point of the PV panel and makes the
system to operate at the MPP which ensures the maximum power is generated from the
PV. This module supports the well documented APIs that aid in application programming.
Typical module functionality includes, starting the MPP tracking algorithm,
enabling/disabling the MPP tracking algorithm and retrieving logged parameters from the
MPPTCore module.
12.3 Lead-Acid battery charging module
This is an optional software library provided along with the MPT612 IC. This module
implements the lead-acid battery charge cycle for 2-stage, 3-stage and 4-stage batteries.
Using the easy configuration for the battery parameters and well documented APIs, the
user can design an application with ease. This module together with the MPT612SW will
help in the creation of power management systems for battery charging for home and
street lighting applications.
12.4 Sample charge controller and load control application
This module implements the sample charge controller and load control application for the
specification of the MPT612 reference board. It uses features of the MPT612SW and
lead-acid battery charging module to implement a typical charge controller application.
12.5 Sample applications
Using MPT612SW and lead-acid battery charging module, solutions for several
applications can be generated such as:
dusk-to-dawn lighting applications
street lighting applications
traffic lighting applications
solar based mobile chargers
DC-DC converters in panels
micro inverters.
In the SW architecture diagram shown in
Fig 5
, SampleApplication1 will interact directly
with MPPTCore module to extract the maximum power which can use a micro-inverter, to
feed it to the grid. SampleApplication2 utilizes the services of the battery charging
algorithm to charge the battery and can be used to control different lighting applications.
