Weight Estimation of Electronic Power Conversion Systems
This thesis presents a procedure to estimate weight of electronic power conversion systems, which provides an angle to evaluate different system architectures. This procedure has three steps. Step I, according to application of the system and system structure, determines the electrical and environmental specifications for each converter in the system. Step II studies the design procedures for each converter in the system and determines parameters such as the wire gauge and length of cable; the parameters of the passive components, such as inductance and capacitance; the parameters of the power switch, such as the voltage rating, current rating and loss; and parameters of the cooling system, such as the thermal resistance of the heat sink. Step III, according to the convertersâ parameters, carry out the physical design and selection of sub-components such as the inductor and heat sink to get the componentsâ weight; the sum of those componentsâ weight is the estimated system weight. This procedure has also been implemented in the form of software â system weight estimation tool. Using this software, weight of sample systems with ac dc bus and two different bus voltages have been estimated and compared.
