Losses in Sinusoidal Filter for Pulse Controlled Converters
Abstract
This paper presents three methods lossesevaluation in magnetic circuits of sinusoidal filter chokes
and their experimental verification. The attention is focused
on losses caused by higher harmonics in context of
frequency pulse width modulation. Methods based on the
calculation of the reference loss method are described, they
are based on direct measurement using an integral of
instantaneous power losses and determining of them from
temperature rise characteristic.
