Traditional air-coupled inductors are usually limited to two phases. This article presents the concept of multiphase 3-D polyhedron air-coupled inductors – termed “origami inductors” – formed by folding planar windings on modular surfaces into symmetric 3-D structures, which enables symmetric air-coupling of more than two phases. The air-coupled origami inductors, unlike traditional multiphase coupled inductors, do not need a magnetic core and can operate at high frequencies. Compared to discrete air-core inductors, the origami inductors can be easily transported and assembled and can offer reduced size, smaller current ripple, and faster transient due to dc and ac flux cancellation. Models are developed to quantify the performance benefits of the origami inductor. A tetrahedron-shaped four-phase origami inductor was designed and through FEM simulations, its reduced volume was verified. The origami …

This paper presents the principles of foldable 3-D polyhedron air-coupled origami inductors and their application in multiphase interleaved MHz power conversion. The polyhedron air-coupled origami inductor comprises of multiple windings forming the surfaces of a closed Euclidean structure, with each of these surfaces representing one phase of the coupled inductor. These windings can be implemented on a printed circuit board (PCB) which can be folded to form the 3-D polyhedron strcutures. Compared to discrete air-core inductors, the polyhedron air-coupled inductor offers reduced volume of flux distribution, reduced current ripple, as well as a faster transient response. A four-phase interleaved boost converter with a symmetric tetrahedron air-coupled inductor as the input inductor was built and tested at switching frequencies from 1 MHz to 10 MHz to verify the principles of the polyhedron air-coupled inductors.

Controlling the multiway power flow in a multi-active-bridge (MAB) converter is important for achieving high performance and sophisticated functions. Traditional feedforward methods for MAB converter control rely on precise lumped circuit models. This article presents a machine learning (ML) method for the feedforward power flow control of an MAB converter without a precise circuit model. A feedforward neural network was developed to capture the nonlinear characteristics and predict the phases needed to achieve the targeted power flow. The neural network was trained with a large amount of data, collected with a set of known phase angles. This trained network was used to predict the phases to achieve the targeted power flow. A six-port MAB converter was built and tested to validate the methodology and demonstrate the “machine-learning-in-the-loop” implementation. Transfer learning was proven to be …

Current balancing of paralleled switches in resonant converters with multiphase coupled inductor

Paralleling power devices is a commonly used technique to implement high-capacity power converters. However, device mismatches and uneven circuit parasitics may cause current imbalance among devices, diminishing the benefits of paralleling. This paper investigates the current balancing mechanism of multiphase coupled inductors in resonant converters against a variety of circuit asymmetries and disturbances. The current balancing mechanism of coupled inductors for multiple parallel switches is explained in theory. A 1 MHz, 250 W resonant dc-dc converter with four GaN switches in parallel was built to test the effectiveness of a coupled inductor for current balancing. Simulation and experimental results show that paralleling multiple switching devices with a multiphase coupled inductor can greatly mitigate the impact of uneven circuit parasitics and gate signal mismatches and ensure current sharing, with …
