Summary: A new dual-buck structure is proposed for three-switch leg converters, which is more reliable and can achieve high-quality output waveforms compared to conventional structures. The performance is verified through experiments in a single-phase dual-output inverter, and it is concluded that the discontinuous modulation scheme can improve the dc-link voltage utilization.

Summary: This article explains the equivalent mechanism between a nine-switch converter (NSC) and two six-switch converters (SSCs) in detail. It introduces the concept of virtual legs and space vector modulation method for achieving decoupling and independent control of NSC, respectively. The proposed modulation method allows NSC to control two sets of three-phase ac voltage independently, achieving the same performance as dual SSCs.

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: The commonly used average model is not applicable to predict the stability performances of constant ON-time (COT) controlled buck converters. It has been reported that stability issues can be addressed by using the output voltage transfer function G(VC) and describing-function approach. However, the actual G(VC) may deviate significantly from the ideal model, emphasizing the importance of measured G(VC) transfer function for real-world stability predictions.

Summary: This article presents a new nonisolated bidirectional dc-dc converter with low voltage and current stresses across the semiconductor devices. The converter is a combination of a dual-stacked bidirectional boost converter and offers synchronous and asynchronous operation modes to reduce current ripple. The article also discusses the modeling and control of the proposed converter. A 1-kW, 144-V/400-V prototype was built to validate the theoretical evaluations, achieving peak efficiencies of 96.33% and 96.87% for step-up and step-down modes, respectively.

Summary: This article presents the evolution of two-switch-based enhanced gain buck-boost converter (EGBBC) topologies, which result in three different topologies with quadratic buck-boost voltage gain. The quadratic buck-boost transformation is achieved by adopting a modified boost configuration at the front-end together with a restructured cascading approach.

Summary: This paper proposes a joint input and state dynamic estimation scheme for power networks in microgrids and active distribution systems to address the limitations of conventional methods under highly dynamic conditions. By utilizing a power network model based on branch currents physical equations and linear Kalman-based dynamic filtering algorithms considering the crosscorrelation between states and inputs, the effectiveness of the proposed method in estimating both state and input variables in a distributed manner is demonstrated. Results from experiments on a 13-bus microgrid system show the superiority of the proposed method over traditional weighted least square and tracking state estimation methods.
