Description: 提出了一种新型的单开关升-降压式(Buck-Boost)直流变换器的电路仿真平均模型。这种模型可通过输
入参数的选择实现对Buck-Boost电路的电压控制、峰值及平均电流控制,以及对DCM-CCM工作方式的统一。它
是一种实用的仿真模型,可方便地进行稳态和动态分析。在保证准确的基础上,大幅度提高了仿真的速度,通常比
用实际器件开关电路的仿真速度提高两到三个数量级。
-A novel average model for single switch Buck-Boost DC/DC converter has been given. Voltage control
mode, peak current control mode and average current control mode can be varied easily by changing the parameter of the
average model. This model can unify continuous conduction mode (CCM) and discontinuous conduction mode (DCM). It
can be used to do static and dynamic circuit analysis. By using this average model the simulation speed can be improved by
2~3 order comparing with the using of switched model.

Description: 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.

Description: 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
