JPtpenov95p680.rar - Abstract: In this paper the SIMULINK model of a PWM controlled DC-DC
converter is modeled using switching function concept to control the speed of the
DC motor. The presence of the voltage oscillation cycles due to higher switching
frequency in the DC-DC converter is identified. The effect of these oscillations
on the output voltage of the converter, Armature current, Developed torque and
Speed of the DC motor is analyzed. In order to minimize the oscillation cycles
the PI controller is proposed in the PWM controller,2012-04-06 02:47:45,下载4次

00460.rar - Abstract: Randomized modulation is of increasing interest in power
electronics and also holds promise for reducing filtering requirements
in ac/ac, dc/dc converter application and reducing acoustic noise in
motor drive applications. This paper deals with the power spectrum
density (PSD) estimation methods of the random controlled pulse
width modulation (RPWM) single-phase structured boost rectifier.
Estimated PSD is also experimentally verified. The switch-mode
operation of the converter results in Electromagnetic Interference
(EMI) which is produced due to large di/dt and dv/dt. In addition to
all steps to minimize the generation of EM1 (i.e. introduction of
RPWM), improvement of power spectra will also be considered.,2012-04-06 02:42:02,下载43次
AN-1067.rar - In higher power applications to utilize the full line power and reduce line current harmonics PFC
Pre-regulators are generally required. In these high power applications interleaving PFC stages can
reduce inductor volume and reduce input and output capacitor ripple current. This results in smaller overall
magnetic volume and filter capacitor volume increasing the converters overall power density. This is made
possible through distributing the power over two interleaved boost converters and the inductor ripple
current cancellation that occurs with interleaving, reference [5]. This application note will review the design
of a 300W two-phase interleaved power factor corrected (PFC) pre-regulator. T,2012-04-06 02:40:45,下载29次
