Summary: A reconfigurable rectifier-based detuned series-series (SS) compensated IPT system is proposed to improve the system efficiency and tolerate a wide coupling range. The reconfigurable rectifier can switch between a full-bridge rectifier mode and a half-bridge rectifier mode to extend the expected coupling range of the detuned SS topology. The system efficiency is also improved by changing the ac load to match the optimal load of the IPT system.

Summary: This paper proposes a resonant modular multilevel rectifier (RMMR) to eliminate charge sharing loss in conventional multilevel rectifiers. The RMMR is applied in a series-series compensated IPT system to achieve independent secondary control for output voltage regulation with low harmonic distortion and reduced conduction loss. Experimental results show a peak dc-dc efficiency of 96.6%.

Summary: This article proposes a synchronized switch harvesting on shared capacitors (SSHSC) rectifier for piezoelectric energy harvesting without the need for bulky inductors or dedicated flying capacitors. The SSHSC rectifier utilizes three energy-storage capacitors with a specific capacitance ratio, serving as both storage and flying capacitors. The capacitor-sharing technique enables a smaller volume and fewer I/O pads compared to prior designs.

Summary: This article proposes a hybrid five-level unidirectional rectifier that combines silicon carbide (SiC) and silicon (Si) to address the cost issue of wide bandgap (WBG) devices in high-power applications. By adding snubber capacitors, all the Si devices operate at low-speed switching, minimizing the voltage stresses of the SiC MOSFETs. The operational analysis and carrier-based phase-disposition pulsewidth modulation scheme for this circuit are discussed in detail, achieving capacitor voltage balancing and unity power factor.

Summary: This article proposes a step-up single-phase seven-level inverter that uses one voltage source and two symmetrical capacitors. The proposed topology generates bipolar levels without an inverting H-bridge, reducing the total standing voltage of switches and resulting in low-voltage stress. The structure has voltage-boosting capability and high efficiency, making it suitable for distributed generation applications. Experimental results verify the feasibility of the proposed topology.
