“…In electric vehicle (EV) applications, a boost converter is usually used to step up the low battery voltage to high DC-Link voltage [5], [6], [7]. On the other hand, low-power DC-DC converters are used in applications such as DC motor drive and intermediate bus converters (IBC) [8], [9], [10], [11], [12]. With the rapid development of DC-DC power conversion technology, conventional inductorbased switching mode power supplies (SMPS) can no longer meet the high efficiency and high power density requirement of the market.…”

This paper demonstrates a high-efficiency modular multilevel resonant DC-DC converter (MMRC) with zero-voltage switching (ZVS) capability. In order to minimize the conduction loss in the converter, optimizing the root-mean-square (RMS) current flowing through switching devices is considered an effective approach. The analysis of circuit configuration and operating principle show that the RMS value of the current flowing through switching devices is closely related to the factors such as the resonant tank parameters, switching frequency, converter output voltage and current, etc. A quantitative analysis that considers all these factors has been performed to evaluate the RMS current of all the components in the circuit. When the circuit parameters are carefully designed, the switch current waveform can be close to the square waveform, which has a low RMS value and results in low conduction loss. And a design example based on the theoretical analysis is presented to show the design procedures of the presented converter. A 600 W 48 V-to-12 V prototype is built with the parameters obtained from the design example section. Simulation and experiments have been performed to verify the high-efficiency feature of the designed converter. The measured converter peak efficiency reaches 99.55% when it operates at 200 kHz. And its power density can be as high as 795 W/in 3 . Modular, multilevel, resonant, resonant DC-DC converter, switched-capacitor, zero-voltage switching (ZVS). INDEX TERMS

“…One or multiple DCX blocks can be used depending on the gain. For the circuit level implementation, LLC (e.g., [139], [140]) and ResSC (e.g., [138], [164]) are commonly used as the DCX blocks. For the regulated block, buck converters are normally used in Sigma converters, and boost converters are normally used in Composite converters.…”
