This paper describes a very detailed and comprehensive description of a model predictive controller (MPC) applied to the buck converter working in Continuous Conduction Mode (CCM) to optimize the performance of the converter. The converter is designed for a fixed switching frequency of 1 MHz. The proposed model predictive control technique achieves improved set point tracking with minimal overs...

This paper presents a wide range maximum power point tracker (MPPT) using fuzzy logic controller for PV sizing and efficiency improvement. The MPPT consists of a buck boost converter, controlled by a fuzzy logic. The fuzzy has two inputs and single output. Inputs are voltage and current of the PV, while the output is duty cycle for the buck boost. The MPPT effectively tracks at average 97.3% of...

In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

The PMBLDC motor is 3 phases, 4 poles, Y connected; trapezoidal back-EMF type of BLDC motor for automotive industry application is modeled and simulated in MATLAB / SIMULINK. A MATLAB program is developed to simulate the overall motor drive system. A closed loop speed control strategy is developed and simulated. The drive system is proposed with a buck converter topology. In this model the buck...
