This paper proposes two linear power sharing schemes for distributed generators in microgrids to reduce total generation costs. The schemes use linear droop functions, which are easier to implement and tune than current nonlinear cost-based schemes. Experimental results show successful outcomes under different operating conditions.
2.
This paper proposes a magnetic integration solution for direct PWM ac-ac converters using coupled inductors. The proposed inductor eliminates the air gap, exhibits symmetrical winding currents, and has a smaller volume with high current handling capability. It can handle unlimited current and is suitable for high power ac-ac conversion applications. The experimental results show that the proposed integration scheme reduces the volume of the coupled magnetic components by more than 50%.
3.
This paper analyzes the fault tolerance capability of six-phase induction motor drives, which are highly valued for their inherent redundancy. The study provides a comprehensive analysis of post-fault derating in generic six-phase machines and specific fault-tolerant capability of three mainstream six-phase induction machines. Experimental results confirm theoretical post-fault current limits and identify the best six-phase machine for each fault scenario and neutral arrangement.
4.
This paper presents a new predictive current controller for high-performance operation of a permanent-magnet synchronous motor drive. The proposed controller combines deadbeat and direct predictive control techniques and achieves improved transient characteristics compared to a typical PI current controller in field-oriented control strategy. Simulated results have been validated by measurements on a test bench.
5.
This paper presents a method for monitoring multiple loads in wireless power transfer systems without wireless communication. The approach uses a mathematical method to scan frequencies and derive load conditions based on input voltage and current. A hardware prototype confirmed the proposal's effectiveness.
