Current-tripler-rectifier ZVS three-phase full-bridge DC/DC converter (CTR-ZVS-FB converter) is a potential alternative for high-power applications due to its desirable characteristics of compact, efficient, high current capability, etc. In some cases, the failure of the power switch results in a converter shutdown and affects the reliability of the entire system. Therefore, this article presents a new remedial fault-tolerant operation for the CTR-ZVS-FB converter. During the remedial working mode, the inductor current, ZVS Soft-Switching Regions, and loss of duty cycle are analyzed. Moreover, this paper simulates the heavy loads of the converter under the remedial fault-tolerant operation. Results convincingly indicate that the proposed control is efficient and capable of running the system during the faults with a slight increase in the inductor current.

With the wide application of power semiconductor devices in severe working conditions, the reliability and lifetime estimation of power semiconductor devices have become the research hotspot. Power cycling test is a significant method to study the reliability issues. This paper first analyzes the existing methods and then proposes a new power cycling method which considers not only realistic electrical conditions but also the thermal stress from different regions. Firstly, rainflow algorithm is used to extract the temperature cycles with large amplitude. Next, the junction temperature cycles and case temperature cycles are matched using integer programming algorithm and modified by means of equivalent substitution. At the same time, a method to control the case temperature and the junction temperature simultaneously is proposed. Afterwards, modified rainflow reconstruction algorithm is used to combine these matched cycles to temperature arrays. Finally, test load profile is formed. An electric vehicle motor drive system based on the Worldwide Harmonized Light Vehicle Test Procedure mission profile is used to verify the proposed method. This method can simultaneously stress the bonding wire and the solder layer, which provides a new way to access the reliability of power devices in real application.

Very high frequency Class E dc-dc converter has been widely investigated for its simple structure and easy realization of soft switching. Constant switching frequency (CSF) ON-OFF control is usually employed to regulate the converter output voltage for the advantage of excellent dynamic performance and easy parameter optimization. However, it is found that with CSF ON-OFF control, the input power of the Class E dc-dc converter during ON mode increases with the increase of the input voltage, leading to increased modulation frequency and thus diminishing the conversion efficiency. In this paper, a switch-controlled capacitor (SCC) modulated Class E dc-dc converter is presented to solve the efficiency depletion problem under high input voltage. With SCC, the resonant branch impedance of the Class E dc-dc converter is increased to reduce the input power under high input voltages, which helps reduce the modulation frequency and improve the conversion efficiency. A 10-W, 20-MHz Class E dc-dc converter is simulated to verify the feasibility and the advantages of the proposed control scheme.

This paper designs an ultrasonic isolated wireless power supply for the gate drive circuit of multi-level converter H-bridge inverter, basing on ultrasonic wireless power transmission (USWPT) technology. Firstly, COMSOL model is used to simulate the coupling transmission medium and its size. Then loss circuit model is used to calculate and predict the USWPT receiving side output voltage. Finally, the experiment proves that the resonant compensation circuit designed can effectively improve the output power of USWPT system. The designed ultrasonic isolated wireless power supply can stably provide about 15V DC voltage for 180 Ω~250 Ω load when it works at 43.7 kHz.

For isolated power converters, both conducted and radiated electromagnetic interference (EMI) are dependent on the common-mode (CM) performance of transformers. This paper proposes an RLC ladder network modeling and its parameter extraction technique to characterize the wideband CM properties of transformers at the circuit level. It is proved that the ladder network covers detailed electric and magnetic parameters, therefore, is more applicable for wideband than commonly used lumped models. The finite element method (FEM) is selected to extract parameters for accuracy. Influential factors on parameters, including geometries and material properties are also presented. With S21 parameter as the evaluation method of transformers’ CM performance, the proposed modeling technique is verified from 100 kHz to 200 MHz on a planar transformer through the comparison between measured and simulated S21 parameter.

High voltage power semiconductor devices with ultra-fast turn-on speed have always been highly desirable for advanced pulsed power applications. In recent years, the wide band gap semiconductor such as silicon carbide (SiC) has been given extensive attention to fabricating high voltage power devices due to its superior material and electrical properties over silicon. Among all SiC power switches, SiC gate turn-off thyristor (GTO) possesses not only high blocking voltage, but also excellent current handling capability and ultra-high turn-on di/dt. This research focuses on the characterization and pulse evaluation of a homemade high voltage SiC p-type GTO. The SiC GTO has a die size of 7.8 mm × 7.8 mm, and it possesses a differential on-resistance of 33.5 mΩ•cm2 and a high forward blocking voltage of 6.3 kV. The SiC GTO was pulsed in a homemade pulse power discharging system. The test results show that the peak current and di/dt of the SiC GTO during turn-on process can reach up to 9.04 kA (14.86 kA/cm2) and 10.70 kA/µs, respectively, indicating that the SiC GTO is very promising for pulsed power applications.

The voltage balancing of neutral point and two flying capacitors is a great challenge in five-level Buck/Boost converter. Based on the principle of phase shift control and the capacitor voltage regulation, the influence of the neutral point voltage regulation on the flying capacitor voltage is first analyzed. Then, a synchronous phase shifting decoupling control method is proposed, which makes the capacitor voltage regulation almost independent of the neutral point voltage and eliminates the coupling of the system. Based on this, the quantitative relationship between phase shift ratio and the increase of neutral point voltage and flying capacitor voltage is derived. This method makes the voltage balance system immune to the inductor current and carrier waveform, the output voltage is not affected by the capacitor voltage regulation, which is conducive to the design and analysis of the controller. The experimental results based on the 1.5 kW prototype verify the analysis results and the excellent voltage balance performance.

This paper presents an underwater wireless power and data transfer (WPDT) system with the shared channel. The power and signal could be transferred with the same channel based on the time division multiplexing theory. In one switching cycle, the power is transferred in the first half switching cycle and the signal is transferred in the second half switching cycle. The signal is modulated with the frequency-shift keying (FSK) method. The frequency for the power delivery is set as 240 kHz. With the FSK modulation method, the frequencies of two carriers are set 10 MHz and 2 MHz for signal transmission, respectively. The glass tank experimental platform is constructed with the 35‰ salinity water. The simulated and experimental results verify the theory analysis and the calculation very well.
