Abstract :
In this paper, a resonant boost converter is analyzed and verified through experimentation. Switching losses are reduced since the converter operates at ZCS (Zero Current Switching). The analysis presented here covers its operation with variable switching frequency but only below the resonant frequency. The range of its voltage gain goes from 1 to 2 and the energy conversion efficiency (including filtering at input) is around 97% for the lowest input voltage. Its envisioned that it could be applied as a front-end converter when a backend inverter is needed, for instance with batteries, photovoltaic converters or fuel cells, perform partial output voltage regulation only.
