Description

This example is intended to show relevant modeling and simulation capabilities of SystemVision Cloud, for kinetic energy harvesting (EH) systems. It is not necessarily a practical EH design itself, but rather demonstrates the tool's ability to support knowledgeable users who are creating practical designs.

The design contains mechanical, magnetic and electronic circuit elements, with energy conservation and cross-discipline dynamic interactions automatically included in the system model. The user can directly specify the physical or behavioral characteristics of many of the components. This includes the mass of the armature, the stiffness of the resonant spring, the cross sectional area of the magnetic core, the number of winding turns, the resistor and capacitor values, as well as the drop-out voltage of the linear regulator.

In the nominal simulation results displayed on the schematic, the upper right waveform viewer shows the initial start-up of the system, with the amplitude of the external vibration source of 0.07 mm peak at 60 Hz, equivalent to a peak acceleration of 1 g. The nominal armature spring-mass resonance frequency is 60 Hz, and the armature displacement is seen to reach the frame's travel limit of 10 mm peak-to-peak!

In the upper left, the waveform viewer is zoomed-in near the 1 sec. simulation time mark. It shows the time-varying core flux density and winding voltage, as the two air-gaps expand and contract with armature displacement, rapidly changing the magnetic flux path's effective reluctance value. In the lower right waveform viewer, the DC output voltage from the Schottky diode full-wave rectifier and the linear regulator output voltage are observed. The periodic disturbance is caused by the switched load being applied to the system.
