<p data-start=”112″ data-end=”416″>I’m trying to determine the simplest way to estimate <strong data-start=”165″ data-end=”181″>power output<\/strong> from a magnetic power harvester modeled in Ansys Maxwell. The device functions similarly to a <strong data-start=”276″ data-end=”299″>current transformer<\/strong>, where a primary conductor carrying AC current induces voltage in a secondary winding connected to a resistive load.<\/p><p data-start=”418″ data-end=”700″>For simplification, the grey cylinder is the conductor, the green cylinder is a magnetic core and the orange loop is the copper winding. I modeled the copper winding as a single-loop representation with defined primary and secondary windings. The conductor is excited with a prescribed AC current (60 Hz), and I am attempting to extract the resulting voltage and current on the coil.<\/p><p data-start=”702″ data-end=”976″>Currently, I’ve assigned both the primary and secondary as <strong data-start=”758″ data-end=”792″>voltage-type windings with 0 V<\/strong> and specified a resistance. However, the simulation results show nearly zero induced voltage and extremely low current on the secondary, so I think the setup might be inaccurate.<\/p><p data-start=”1782″ data-end=”1894″>Any guidance on the correct\/ simple setup for extracting voltage and power would be greatly appreciated.<\/p><\/p>\n
