چکیده
In electric drive systems common mod voltage (CMV) is known as between power line and ground. CMV causes negative effects on both engine its driver whereas switching operation occurs in devices. addition frequency multiples cause electromagnetic aqustic noises. this paper a novel Fixed-Frequency chaotic switched sinusoidal pulse width modulation (FFCS-SPWM) proposed. The cruial point proposed FFCS-SPWM method to obtained new carrier wave by summation of inverse form. extra loses were reduced due constant frequency. This also applied permanent magnet synchronous motor (PMSM) vector control system. reduction interference (EMI), noises dv/dt stress that occur simulated method. Moreover SPWM combined with chaotic-frequency (CFCS) reduce the differential mode (DMV) which lines . Finally change chaotically it shown that, CFCS-SPWM provides EMI, are caused DMV

متن کاملan Efficient Drive Circuit for Switched Reluctance Motor
The purpose of this paper is to present an efficient converter circuit used to drive switched reluctance motors. It uses the C-dump topology in which the trapped energy in the phase windings is returned to the supply capacitor to be used in the following strokes. In addition to the C-dump topology, it uses two extra feedbacks. One comes from a governor mounted on the shaft of motor which contro...
متن کاملA comparative study of carrier-frequency modulation techniques for conducted EMI suppression in PWM converters
A rigorous mathematical analysis and a comparative study of carrier-frequency modulation (CFM) techniques for the conducted electromagnetic interference (EMI) suppression in pulsewidth-modulated converters is presented. CFM techniques dither the switching period with a small amplitude variation around the nominal value, so that the harmonic power is redistributed over the spectrum of concern. T...

Auditory Electrical Stimulation for Tinnitus Suppression Tinnitus is the conscious experience of sound which arises in the head of its owner, but without a voluntary origin obvious to that person. About 10-15% of all adults report prolonged spontaneous tinnitus (PST). There are a lot of methods for suppressing this complaint. One of these methods is electrical stimulation. Electrical stimu...
