TL;DR: There is a need for the DC-DC converter for the mitigation of current harmonics and to increase power factor at the input ac mains, so cuk converter is used as a power factor correction converter.
Abstract: This work deals with performance enhancement of the permanent magnet brushless direct current (PMBLDC) motor drive. The ac-dc conversion of electric power is usually required for the BLDC motor drive, nevertheless it causes many current harmonics and poor power factor at the input ac mains. There is a need for the DC-DC converter for the mitigation of current harmonics and to increase power factor at the input ac mains, so cuk converter is used as a power factor correction converter. The PMBLDC motor drive is analyzed in MATLAB/SIMULINK environment and relevant hardware outputs are presented.

TL;DR: In this paper, weak periodic perturbation (WPP) is applied to stabilize an unstable orbit in a current-mode controlled Positive Output Luo (POL) DC-DC converter operating in a chaotic regime.
Abstract: A simple, non-feedback method of controlling chaos is implemented for a DC-DC converter. The weak periodic perturbation (WPP) is the control technique applied to stabilize an unstable orbit in a current-mode controlled Positive Output Luo (POL) DC-DC converter operating in a chaotic regime. With WPP, the operation of the converter is limited to stable period-1 orbit that exists in the original chaotic attractor. The proposed control strategy is implemented using simulations and the results are verified with hardware setup. The experimental results of the converter with WPP control are presented which shows the effectiveness of the control strategy.

TL;DR: In this paper, a LCL filtered power factor corrected (PFC) converter to feed permanent magnet synchronous machines (PMSM) having field-oriented control (FOC) method has been proposed.
Abstract: In this paper, a LCL filtered power factor corrected (PFC) converter to feed permanent magnet synchronous machines (PMSM) having field-oriented control (FOC) method has been proposed. In order to compensate the total harmonic distortion (THD) and poor power factor (PF) problem while achieving the high efficiency and reducing the switching losses of the converter and the voltage source inverter (VSI), the proposed system has been designed as LCL filtered bridgeless single-stage PFC isolated cuk converter for low power applications. Value of the output inductor provides discontinuous conduction mode (DCM) operation for reducing the conduction losses on switches of the converter. On the other hand, source filter was designed as LCL type to ensure power quality improvement. Results of this paper through the simulation have demonstrated that the proposed system has a capability to drive low power applications within the boundaries of international power quality standards and speed of the PMSM was controlled as desired.

TL;DR: In this paper, the authors proposed the use of high-order elliptic filters to achieve the required EMI attenuation and power factor, which provides a significant filter size reduction over the standard filter, minimizes the filter-power converter interaction, and maintains a good converter power factor.
Abstract: The issues involved in the design of power factor correction circuit input filters are significantly different from those involved in the design of input filters for DC-DC power converters. In many cases, the EMI and power factor requirements are impossible to meet using the existing filtering technology. This paper proposes the use of high-order elliptic filters to achieve the required EMI attenuation and power factor. The new input filter technology provides a significant filter size reduction over the standard filter designs, minimizes the filter-power converter interaction, and maintains a good converter power factor. New active and passive filter damping methods that guarantee optimal filter pole damping, while virtually eliminating damping resistor power dissipation, are proposed. The filter design procedure that makes possible a simple and fast design of filters with an arbitrary number of stages is also presented.

TL;DR: In this paper, a high order, actively damped filter is proposed to achieve the required EMI attenuation and power factor requirements for high-frequency AC power converter input filters.
Abstract: The issues involved in the design of power factor correction circuit input filters are significantly different than those involved in the design of input filters for DC-DC power converters. So far, there exist no guidelines for high-frequency AC power converter input filter design. This paper addresses these issues and proposes the use of a high order, actively damped filter to achieve the required EMI attenuation and power factor requirements. The new filter topology typically provides 50% filter size reduction over the standard filter designs, and simultaneously minimizes the filter-converter interaction. >

TL;DR: In this article, a closed-loop Cuk converter with the aid of the equivalent control method is obtained with the assistance of the Routh-Hurwitz stability criterion and root locus, and a stable and robust system suitable for large signal variations is achieved.
Abstract: Proportional-integral (PI) and sliding mode controls are combined to regulate a fourth-order Cuk converter in a continuous conduction mode. A closed-loop system is obtained with the aid of the equivalent control method. Based on the Routh-Hurwitz stability criterion and root locus, the appropriate PI gains are obtained and a stable and robust system suitable for large signal variations is achieved. The minimum or nonminimum phase behavior of the closed-loop system and the transients of the closed- loop system under step variations of various circuit parameters are analyzed. Under a wide range of operating points, the Cuk converter under the proposed controller has a load voltage tracking accuracy within ±0.05 V with a moderate maximum switching frequency of not greater than 100 KHz. The merits and demerits of the proposed controller are compared with some other controllers.

TL;DR: Simulated results are presented to demonstrate an improved power quality at ac mains of the PMBLDCMD system in a wide range of speed and input ac voltage.
Abstract: This paper deals with a Cuk dc-dc converter as a single-stage power-factor-correction converter for a permanent-magnet (PM) brushless dc motor (PMBLDCM) fed through a diode bridge rectifier from a single-phase ac mains. A three-phase voltage-source inverter is used as an electronic commutator to operate the PMBLDCM driving an air-conditioner compressor. The speed of the compressor is controlled to achieve optimum air-conditioning using a concept of the voltage control at dc link proportional to the desired speed of the PMBLDCM. The stator currents of the PMBLDCM during step change in the reference speed are controlled within the specified limits by an addition of a rate limiter in the reference dc link voltage. The proposed PMBLDCM drive (PMBLDCMD) is designed and modeled, and its performance is evaluated in Matlab-Simulink environment. Simulated results are presented to demonstrate an improved power quality at ac mains of the PMBLDCMD system in a wide range of speed and input ac voltage. Test results of a developed controller are also presented to validate the design and model of the drive.
