This paper proposes a design and control approach to parallel resonant converter (PRC) based battery chargers. The proposed approach is particularly suitable for the constant-current constant-voltage (CC-CV) charging method, which is the most commonly utilized one. Since the PRC is operated at two different frequencies for each CC and CV charging modes, this approach eliminates the need for complicated...
Currently, electrical engineers have been focused on Brushless Direct Current (BLDC) motor drives because of their efficiency, low maintenance, low inertia, high torque-weight ratio and simple control. Conventional inverter circuits for BLDC motors includes six power switches. Whereas in this paper, a BLDC drive system with four switch inverter and a voltage controlled BLDC drive is presented to reduce...
The Parallel Resonant Converters (PRC) are commonly equipped with a high frequency transformer (HFT), in order to provide an isolation and to adjust the current/voltage values. This study, investigates the effects of HFT on the operation of PRC, by utilizing Bode Diagrams. Simulation results are presented.
This study presents a detailed approach to extend the conventional state plane analysis (SPA) of the parallel resonant converter (PRC) by including some non-ideality sources which might influence the operation of the circuit. It is experimentally shown that the proposed method improves the SPA of PRC dramatically.
This work presents a simple control and design approach for parallel resonant converters (PRC) for battery charger applications in renewable energy sources (RES). The proposed method particularly aims to operate the PRC in accordance with the Constant-Current Constant-Voltage (CC-CV) Charging Method, which is frequently applied for various battery types. In contrast to traditional resonant converter...
This work presents a comparison between different tuning methods for cascade PI(D) controller parameters of the permanent magnet direct current (PMDC) motor drives. First, the classical method (CM) for cascade PI(D) tuning is explained and applied. It has been shown that the classical tuning approach requires some assumptions. Next, a heuristic optimization technique, the Bacterial Foraging Algorithm...
It is commonly accepted that the efficiency of a wireless energy transfer (WET) system depends on the resonance components and mutual inductance of between coils. Before the finite element analysis, applying analytical methods make the design procedure of resonance components faster and reliable. In this paper, some analytic methods are investigated to find values of self-inductance, intra-winding...
One of the challenging problems of Wireless Energy Transfer (WET) is to provide higher efficiency values in spite of decreasing in mutual inductance between coils. For this reason, the study presents some limits such as the critical height and critical winding pitch of coils. This paper also proposes calculation methods for resistance, inductance and quality factor of coils with small error. These...
