New Solution Technique for the Frequency and Transient Response of Transformer Windings with All Inter-Turn Mutual Inductances and Capacitances Included
Abstract: This paper addresses the frequency response, the identification of the resonance frequencies as well as the transient response of transformer windings taking into account all possible inter-turn mutual inductances and capacitances. The mutual inductances and capacitances between any turn to all other turns, i.e., not only the immediately adjacent ones, are considered. The analysis starts with writing the set of simultaneous differential equations relating the currents and voltages within the …

Cell Balancing in Lithium-ion Batteries – A Comparative Evaluation
Abstract: Balancing the cells within a battery system is essential for safeguarding against overvoltage, overcharge, and over-discharge, which can lead to system failures and safety hazards. Two commonly employed methods for cell balancing are passive and active balancing. In passive balancing, excess charge is dissipated through resistors, while active balancing involves the controlled flow of charge within the circuit. This paper focuses on the comparison and analysis of passive and two …

The Transient Response and Frequency Characteristics of Power Transformers having Non-uniform Winding Insulation
Abstract: This paper presents a Laplace-domain distributed-parameter technique for analyzing the transient and frequency response of power transformers having non-uniform winding insulation. Stronger winding insulation near the windings source side terminals is usually applied in order to mitigate the concentration of the transient voltage stresses close to these locations. This will result in a location-dependent inter-turn capacitance distribution. The suggested procedure for analyzing such windings is based on the cascade connection …

The Transient Performance of Power Line Towers
Abstract: This paper presents a refined approach to the transient analysis of power line towers. Each section of the tower’s steel structure is accurately modeled as a non-uniform transmission line. Among other features, an efficient representation of the towers’ cross-arms as open-ended non-uniform lines and their subsequent approximation by lumped capacitors will be explored. Furthermore, the error introduced by neglecting the presence of the cross-arms, as well as the effect of …

SPICE Modeling of LDMOSFET Transistor
Abstract: AbstractHigh voltage integrated circuits, these days are the most viable alternatives to discrete circuits for various applications. The popular amongst them is the lateral double diffused MOS transistor (LDMOS). It is based on the lightly doped drain (LDD) concept. The constraint that occurred in modeling LDMOS is to minimize the on-resistance along with maintaining a high breakdown voltage. To achieve the objective, the help of RESURF (Reduced Surface Field) concept …

Adoption Barriers to Advanced Reproductive Technologies in the Subsistence Dairy Farming Systems: Key Constraints and the Way Forward
Abstract: The adoption of advanced reproductive technologies (ARTs) in subsistence dairy farming remains limited despite their potential to enhance genetic improvement, fertility rates, and overall productivity. This study explores the key constraints hindering the integration of ARTs, including artificial insemination, embryo transfer, and ovulation synchronization, within small-scale dairy production systems. Financial constraints, lack of awareness, inadequate veterinary support, and socio-cultural resistance are identified as primary barriers. Limited access to affordable credit, …

Spice Circuits for Optic Cellular Receiver Simulations
Abstract: A circuit-theoretic approach to the generation of equivalent circuit models of optoelectronic and integrated photonic receiver applications is presented, especially optical cellular receiver systems. In a conventional circuit, the parameters of nano-inductance, nano-capacitance, impedance and scattering (S) parameters can be effectively applied to the analog equivalent representation of a conventional circuit. In a fiber-optic system, those parameters can be used in an integrated photonics and optoelectronic and nanoelectronic circuit as …
