Heat transfer in internal combustion engines is one of the most significant topics. Heat transfer may take place through thermal conduction and thermal convection in spark ignition engines. In this study, valve cover heat transfer and thermal balance of an air-cooled engine are investigated experimentally. The thermal balance analysis is a useful method to determine energy distribution and effi...
In this paper, a bidirectional DC-DC converter with high power density for energy storage application is proposed. The presented converter provides power transfer in both directions only with adjusting phase shift angle. Zero voltage switching (ZVS) in both turn on and turn off moments of all switches is the major capability of the converter that makes it suitable for high power applications. Z...
In this paper, we analyse and demonstrate an energy-harvesting generator powered by continuous rotation, using gravitational torque to enable a single point of attachment. The electro-mechanical behaviour of the generator is presented, alongside experimental results from an implementation based on a conventional dc motor. The off-axis performance is also modelled. The design and experimental re...
The simplicity and low cost of capacitive interfaces makes them very attractive for wireless charging stations and galvanically isolated power supplies. Major benefits include low electromagnetic radiation and the amenability of combined power and data transfer over the same interface. We present a capacitive power transfer circuit using series resonance that enables efficient high frequency, m...
This paper presents a survey of recent wireless power transfer systems. The issue of wireless power transfer is to achieve a highly efficient system with small positioning errors of the facilities setting. Several theories have been presented to obtain precise system design. This paper presents a summary of design theory for short range power transfer systems and detailed formulations based on ...
The capacitive power transfer (CPT) system and inductively power transfer (IPT) system are the two typical wireless power transfer systems. Based on the power transfer characteristics, the power transfer capacity of the two wireless power transfer systems were analyzed. Firstly, the maximum power transfer capacity and its existing condition of the two wireless power transfer systems were analyz...
