“…Consequently, the energy can be delivered to the authorized receiver effectively while avoiding the energy transferred to the unauthorized receiver. In order to avoid code-breaking, chaotic encryption has been developed [78]. When several receivers are coupled to a single transmitter, the bifurcation phenomena might occur due to the varying reflected impedance in the primary.…”

Abstract:With ever-increasing concerns for the safety and convenience of the power supply, there is a fast growing interest in wireless power transfer (WPT) for industrial devices, consumer electronics, and electric vehicles (EVs). As the resonant circuit is one of the cores of both the near-field and far-field WPT systems, it is a pressing need for researchers to develop a high-efficiency high-frequency resonant circuit, especially for the mid-range near-field WPT system. In this paper, an overview of resonant circuits for the near-field WPT system is presented, with emphasis on the non-resonant converters with a resonant tank and resonant inverters with a resonant tank as well as compensation networks and selective resonant circuits. Moreover, some key issues including the zero-voltage switching, zero-voltage derivative switching and total harmonic distortion are addressed. With the increasing usage of wireless charging for EVs, bidirectional resonant inverters for WPT based vehicle-to-grid systems are elaborated.

-The main objective of this paper is to design DC-DC MPPT circuit using chaotic pulse width modulation to track maximum power from solar PV module for space application. The direct control method of tracking is used to extract maximum power. The nominal duty cycle of the main switch of DC-DC SEPIC converter is adjusted so that the solar panel output impedance is equal to the input resistance of the SEPIC converter which results better spectral performance in the tracked voltages when compared to conventional PWM control. The conversion efficiency of the proposed MPPT system is increased when CPWM is used as a control scheme

“…The HF models of different types of motor drives for the investigation and prediction of EMI are discussed in [2]- [20]. In [2]- [12], analytical and numerical approaches are presented, which propose a simulation model for a complete drive system based on the frequency domain. References [13]- [20] present ideas to develop HF model for a motor-drive system based on the circuit measurements.…”

In this paper, a physics-based high-frequency (HF) model of switching power converters including the insulated gate bipolar transistor (IGBT) unit cells, heat sink, and connective printed circuit board (PCB) traces combined in a single electrical circuit is presented. The IGBT model includes the HF stray components superimposed on the well-known Hefner IGBT model. The HF components were calculated using a 3-D quasi-static finite element (3-D FE) analysis. The proposed complex model of the IGBT was verified both numerically and experimentally at different switching frequencies. The computed IGBT model was used in a low-high frequency model of a motor-drive system, and the common mode ground current was experimentally verified showing excellent results.Index Terms-Electromagnetic interference (EMI), electromagnetic compatibility (EMC), finite elements, high-frequency (HF) modeling, power semiconductor switches.
