摘要

Combining low-voltage power sources with loads that require high-voltage levels is a challenge, especially for power devices above 500 W. In this context, this study presents a new dc-dc high-gain converter using coupled inductors. The new converter uses only one switch and output capacitors with low values. It also allows the use of energy from the leakage inductors and enables the input current to operate in the continuous mode. The experimental concept validation was carried out in a prototype of 1 kW with an input voltage between 48 and 96 V and an output voltage of 800 V. The results obtained were coherent, with no significant semiconductor over-voltage and high efficiency was achieved for a wide power range.
