Description
Technical field [0001] The invention belongs to the field of power electronics, and particularly relates to a four-phase interleaved parallel high-power density DC-DC converter for drones and a control method thereof. Background technique [0002] The emergence of unmanned aerial vehicles has helped humans complete many dangerous and complex tasks that are impossible for manned aircraft. While improving the flexibility and maneuverability of detection, it has also effectively reduced casualties. The UAV platform is composed of systems such as power supply, radar, imaging, flight control and data transmission chain. Realizing the long endurance of the UAV and the stable operation of the airborne equipment requires the design of a lightweight and high-efficiency power converter. With the continuous development of industrial-grade drone technology, industrial-grade drones will show explosive growth in multiple industries in the future. [0003] Since the drone uses a 55-63v power bat...
