A Voltage Hexa-Lift and Output Triple Stacked Boost Converter Suitable for Renewable Applications

Please take note of the following text:The boost topology is the most popular non-isolated DC-DC converter with step-up capability. It’s worth noting that lower duty cycle percentages, which lead to higher efficiencies, can only provide a voltage gain from unity to two, which may not be suitable in some cases. This study introduces an improved topology of the boost converter. The provided voltage gain is six times that of a traditional boost converter. This means that a 50 % duty cycle provides a 12-times voltage gain. Similar to the boost converter, the input current is continuous, and only one switch with a simple drive circuit is used. The output voltage of the converter is divided among three capacitors, resulting in decreased output capacitor voltage stress due to the provided triple-stacked structure. The converter is discussed in both ideal and non-ideal modes. Finally, experimental results for a 150 W output power and 600 V output voltage are presented.
