Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

Abstract: Grid-connected full bridge inverters typically have a bulky electrolytic dc capacitor to absorb the unbalanced power from the ac side. The electrolytic capacitors are vulnerable and normally ...

Abstract: This paper proposes a circuit topology and a control strategy to expand the speed range of an open-end winding interior permanent magnet synchronous motor by dual inverter topology. In the ...
