Review of High-Frequency High-Voltage Conversion-Ratio dc-dc Converters
The development of high-frequency power converters is continuously improving their power density, efficiency and fast dynamic response. Among them, highvoltage-conversion-ratio dc-dc converters are widely used in high gain, i.e. step-up/-down or bidirectional applications, such as power supply for data center, dc micro-grids, electrical vehicle charging systems and so on.
In this article, the current main high-frequency high-voltage-conversionratio dc-dc converters are classified into inductive-based and capacitive-based approaches, which can then be described further by four kinds in detail, namely transformer-based, coupled-inductor-based, and switchedcapacitor-based, as well as combination of coupled inductor and switched capacitor.
A comprehensive analysis and comparison is given, which can provide guidance for proper topology selection and further topology optimization.
