Abstract
This article presents the concept and research results of a low voltage nonisolated switch-mode step-down DC-DC converter in a new topology favorable for high-frequency operation. In the proposed converter, the voltage across the components and the inductance of the choke are reduced. Voltage reduction is achieved by the implementation of an appropriate topology, in which modulation is carried out from the input voltage predivided into three capacitors. For such a system, the results characterizing its modulation, voltage and current stress, and efficiency are presented. The proposed converter provides continuous voltage regulation, and a low-complexity PWM generator is required for its proper operation. The article also presents a method of natural voltage balancing in the proposed converter with three-capacitor input divider. This method does not require voltage measurements or any special control strategy and may be more reliable in high-frequency systems than active methods based on modulation correction. The article presents an experimental validation of the feasibility, proper operation and parameters of the proposed converter. The reported results include operation at 48-V-to-12-V and 48-V-to-5-V conversion ratios, demonstrated on a GaN-based converter operating at a 1.2-MHz switching frequency. Such a converter can be used in growing technologies such as 48 V mild hybrid vehicle systems and data centers.
