sinusoidal current การใช้

This non-sinusoidal current leads to harmonic distortion and a poor power factor in the AC supply.
To measure the real power or reactive power, a wattmeter designed to work properly with non-sinusoidal currents must be used.
A purely reactive component is distinguished by the sinusoidal voltage across the component being in quadrature with the sinusoidal current through the component.
It should be possible to get better efficiency by using sinusoidal currents, which could be approximated from a battery supply through suitable electronics.
Utilizing the gating signals developed for a VSI and a set of synchronizing sinusoidal current signals, results in symmetrically distributed shorting pulses and, therefore, symmetrical gating patterns.
