Abstract :
A non-isolated high-gain boost converter using a voltage-stacking cell is proposed. The voltage gain can be increased by adjusting the number of voltage-stacking cells and the transformer turns-ratio. Test results with a 1 kW prototype converter show that voltage gain is three or four times higher than the conventional boost converter at the unity transformer turns-ratio and about 90% of efficiency is recorded under full load condition.
