This paper describes the system concept and initial results for end-to-end energy-autonomous sensor systems using unmanned aerial vehicles (drones) as agents for power delivery to and data gathering from sensing devices. Such systems may be particularly useful for delay tolerant monitoring scenarios, where sensing devices may be deployed in remote, harsh conditions, often with sparse connectivity,...
Traditional rectifiers such as the half-wave and full-wave rectifiers have been the only configuration used in resonant inductive links. Despite their popularity, their input current contains a large amount of harmonics which makes them incompatible with resonant inductive links especially those driven by a Class D or Class E resonant inverter. This paper presents a half-wave Class D voltage-switching...
