AB1 To design and build a zero-voltage-transition step-up dc-to-dc converter
Soft-switching techniques are used to reduce the switching losses in power converters. Zero-voltage-transition and zero-current-transition are the two recently proposed techniques used to achieve this. In this project, a step-up dc-to-dc converter operating with zero-voltage-transition is to be designed and built in the laboratory. The specifications of the converter are: Input voltage (dc) = 25 to 32 V. Output dc voltage = 120 V. Switching frequency = 200 kHz. It is also preferred to simulate the designed converter before implementing it.
AB2 To design and build a zero-voltage-switching dc-to-dc converter
A full-bridge zero-voltage-switching dc-to-dc converter overcomes the problems of conventional hard-switching bridge converters. In this project, a full-bridge fixed-frequency zero-voltage-switching 1 kW dc-to-dc converter is to be designed with the following specifications: Input dc voltage = 250 V. Output dc voltage = 48 V. Switching frequency = 200 kHz. Proper circuit is to be incorporated to solve the problem with the output bridge rectifier oscillations.
AB3 To design and build a dc-to-dc converter for charging electric vehicle batteries
A resonant converter using LCL-type configuration is to be designed and implemented. The converter is coupled to the vehicle using a clamping type high-frequency transformer.
AB4 Other Projects
Any project of interest to the student, but related to power electronics and drives. The project can also be analysis or simulation of a converter.
