Summary: An emerging topology known as the semi-dual-bridge resonant isolated dc-dc converter (SDBRC) is suitable for applications that require unidirectional power transfer and wide buck-boost voltage conversion range. This article proposes a three-level SDBRC and analyzes its operation principle, deriving transfer power and voltage conversion ratio as functions of two phase shifts. A coordinated control rule for the two phase shifts is suggested to ensure monotonicity between the phase shifts and average output power over the power/voltage range. The proposed topology reduces voltage stress on power devices and effectively reduces cost and ON-state loss of power switches, validated through detailed simulations and experiments.

Summary: A switching capacitor-based boost converter topological evolution is proposed in this article, along with the introduction of four enhanced gain boost topologies with common ground feature. These topologies are capable of achieving high-voltage transformation ratio at smaller duty ratios, and load voltage regulation can be ensured through small adjustments in the duty cycle. Among them, DSSCFO Type-2 exhibits both low source current ripple and high voltage gain.

Summary: This article examines a recently proposed dc-dc converter, the Low Energy Storage Quadratic Boost Converter (LES-QBC), and utilizes the Particle Swarm Optimization (PSO) algorithm to optimize the selection of capacitors. It presents a method for selecting capacitors that minimizes the Output Voltage Ripple (OVR) while meeting the constraint of maximum stored energy in the capacitors. Experimental results demonstrate the effectiveness of the proposed optimization approach, achieving a reduction in OVR compared to the non-optimized LES-QBC.

The assessment shows a significant reduction in stored energy in inductors when compared to the other converters. Simulation and experimental results validate the advantages of the proposed dual-switch high step-up power converter.
