Output Voltage Regulation of High Voltage Gain Non-isolated DC-DC Boost Converter
Subject area: Science,Engineering and Technology · Area of research: Power Electronics
Abstract
This paper features a high voltage dc-dc boost converter based on the 3-state switching cell for divided clamped-inverters with neutral split-point. A study of the proposed converter is carried out taking into account the operation in continuous conduction mode and the duty cycle of overlapping mode is greater than 0.5. The key characteristics of topology are the high-frequency operation of the input inductor, whereas, for two times the frequency, the voltage pressure across the switch is lower than half the output voltage and naturally clamped by the one output Capacitor to minimize weight and volume, which enables MOSFET transistors with reduced intrusion ON-resistance to be used. The output voltage can be further enhanced by increasing the transformer turning ratio without compromising voltage stress across the switches; and the output voltage is of course balanced, making the converter ideal for supplying divided-up inverters. In the literature initially, several topologies where high voltage increases are possible are examined. To verify the theoretical study and demonstrate converter efficiency the theory of operation and experimental results for the 1-kW prototype were presented.
