Efficient DC-DC Converter Power Supply for Wireless Sensor Nodes

The first step is a market study on available DC-DC converters. The tasks are to design the electric circuits and evaluate the efficiency. Unlike simple consumer loads, the typical duty cycling of wireless sensor nodes causes a specific load characteristic that has to be regarded. The main objective is to make best use of the energy stored in a supercap. Optionally the output voltage of the DC-DC converter is not fixed, but adjustable by software, e.g. using a software controllable resistor.
