Abstract

Lagrangian Drifters are autonomous foating passive devices that provide oceanographic surface data. They are low-cost, low-power and easy-deployable marine instrumentation used in climate research. One of the main challenges of drifters is energy autonomy. Wave Energy Converters (WEC) have proved their viability in high-power electric generation plants to work as Kinetic Energy Harvesters (KEH) [1] and now they are also showing up at smaller power rate applications in order to power devices such as ocean buoys and drifters [2]. In this latter case, a wise and efcient energy management is crucial to maximize the lifespan of the device. To achieve this goal, a Power Management Unit (PMU) is used, which can also include a Maximum Power Point Tracker (MPPT) to extract maximum energy from the KEH device.
