In this paper a 1 kW series-series compensated, two transmitter four receiver common DC bus parallel connected inductive power transfer system is introduced. The aim is to obtain a modular system with increased reliability and fault tolerance. The system is designed to replace slip rings and brushless exciters of field excited synchronous machines, which require regular maintenance. A generalized critical coupling formula that avoids bifurcation is presented. The system can be easily mounted around a rigid shaft with modular structure and eddy-loss on the shaft is minimized with the novel coil geometry. Finally, with an experimental setup the design is presented.

Concurrent operation of wireless power transfer based contactless slip ring and motor drive system with a single converter Ayaz, Enes; Keysan, Ozan; Department of Electrical and Electronics Engineering (2022-9) This thesis presents a novel approach for concurrent power transfer to wired and wireless systems using a single inverter. This proposed approach fits a cost-effective solution to wireless power transfer (WPT) systems used in contactless slip rings (CSR) applications such as sensors, radars, or wind-turbine pitch controls. In conventional systems, there are two separate converters: one is for the motor drive, and the other is for the WPT system. It is proposed that the switching harmonics of the motor drive...
Carrier Phase Shift Method of SPWM for Concurrent Wired and Wireless Power Transfer Systems Ayaz, Enes; Altun, Ogün; Keysan, Ozan (2022-01-01) This paper presents an approach for concurrent power transfer to wired and wireless systems using just a single inverter. The approach utilizes a novel carrier phase-shift (CPS) method that independently controls the inverter output voltages at the fundamental and switching frequencies. This proposed method can be a cost-effective solution to wireless power transfer (WPT) systems used in contactless slip rings (CSR), which transfer power to auxiliary loads such as sensors, radars, and IoT devices. There are...
Generalized Model of Modular Two Element Compensated IPT Systems with Common DC-Bus Ayaz, Enes; Altun, Ogün; Polat, Hakan; Keysan, Ozan (2022-01-01) In this paper, modular IPT systems which have receiver series/parallel compensation with series/parallel common DC-Bus are investigated. For these systems, power sharing between the receiver modules is vulnerable to system components such as the mutual coupling between the transmitter and the receiver coils. It is also observed that the power sharing is affected by the compensation topologies of the receivers and the type of the electrical connection of common DC-Bus. Therefore, in this study, a mathematica...
Fault Tolerant Multi-Tx/Multi-Rx Inductive Power Transfer System with a Resonator Coil Ayaz, Enes; Altun, Ogün; Polat, Hakan; Keysan, Ozan (2022-01-01) This paper presents a novel multi-transmitter (Tx) / multi-receiver (Rx) inductive power transfer system. Compared to conventional single-Tx/single-Rx systems, multi-Tx/multi-Rx topologies increase reliability and fault tolerance. However, unequal power distribution is challenging in these systems due to coupling differences, which prevents them from operating at rated power or requires over-designed modules. This study proposes the addition of a middle-stage resonator (MSR) that balances power distribution...
Highly Integrated 3 V Supply Electronics for Electromagnetic Energy Harvesters With Minimum 0.4 V-peak Input Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2017-07-01) This paper presents a self-powered interface enabling battery-like operation with a regulated 3 V output from ac signals as low as 0.4 V-peak, generated by electromagnetic energy harvesters under low frequency vibrations. As the first stage of the 180 nm standard CMOS circuit, harvested signal is rectified through an ac/dc doubler with active diodes powered internally by a passive ac/dc quadrupler. The voltage is boosted in the second stage through a low voltage charge pump stimulated by an on-chip ring osc...
