Battery Charging with Maximal Peak Power TrackingMotors and generators with MotorSolve
A maximal peak power tracking (MPPT) example for wind power plant is implemented in this example. The load is a battery that is subjected to a variable speed, realistic wind profile. The system simulated consist of the following components; a wind turbine, a planetary gear system, a generator, a load (battery) and a 3-phase bridge regulator for the generator. The example presented demonstrates the utility of an integrated design process. Comparisons are made between an FEA based machine model and an analytic approximation, a simple example of the utility of such mechatronic simulations.

METHODS and RESULTS
WIND POWER GENERATOR
GENERATOR as a VHDL-AMS MODEL
A VHDL-AMS model of the generator is exported from motorSolve BLDC. The VHDL-AMS interface is shown here. The link allows the user to carry out load and velocity driven simulations as a multiple-input-multiple-ouput black box. Scaling relations of Maxwell's equations can help to carry out design iterations without the need for regenrating new models.
