High voltage power supply system for tethered drone part II

Bongini, Clément
June 11, 2021

A high voltage power supply system for a tethered drone is presented. The project is a follow-up to a previous semester project and the purpose of this project is to review the implementation, improve the design and solve problems. The system consists of an inverter part, a transformer part and a rectifier part. The input voltage is 600 VDC and the output voltage is 12VDC for a maximum power of 1500W. The inverter part is composed of 4 transistors controlled by two gate drivers. On the other side of the transformer, we have a bridge rectifier which will be implemented in 3 different ways: a full-bridge diode and two new active rectification systems, including mosfets and controllers. We will first present the different systems chosen, review the previous part and make improvements, then we will implement these new systems, design the prototypes and make tests for each system. Finally, we will test the whole converter.
