- Abstract:
- This work presents an analysis of a harvesting system of vibratory energy through a variable capacitor and a DC-CD Buck converter circuit. A switch circuit architecture of the Buck converter is presented. The performance of the switch in relation to the wasted energy due to the size of the used transistor as well as the work tension over the switch was verified. The circuit was developed in the cadence scheme and it used components with 0.35 μm technology of high voltage in order to support tension up to 50 V. This circuit presents a loss smaller than 4% of the transferred energy.
