“…Soft-switching universal converters are another category of power converters that are designed to switch at zero current or zero voltage. These converters can be configured as DC-DC, DC-AC, AC-DC, AC-AC, or hybrid power converters, and are excellent candidates for mobile energy systems [104]- [106]. In [107], a compact and efficient universal power converter is proposed for EV application.…”

Mobile platforms cover a broad range of applications from small portable electric devices, drones, and robots to electric transportation, which influence the quality of modern life. The end-to-end energy systems of these platforms are moving toward more electrification. Despite their wide range of power ratings and diverse applications, the electrification of these systems shares several technical requirements. Electrified mobile energy systems have minimal or no access to the power grid, and thus, to achieve long operating time, ultrafast charging or charging during motion as well as advanced battery technologies are needed. Mobile platforms are space-, shape-, and weight-constrained, and therefore, their onboard energy technologies such as the power electronic converters and magnetic components must be compact and lightweight. These systems should also demonstrate improved efficiency and cost-effectiveness compared to traditional designs. This paper discusses some technical challenges that the industry currently faces moving toward more electrification of energy conversion systems in mobile platforms, herein referred to as E-Mobility, and reviews the recent advancements reported in literature. INDEX TERMS Battery technology, fast charging, high-frequency magnetic materials, high-power-density converters, hybridized battery systems, more electric powertrains, wireless charging. I. INTRODUCTION Next-generation mobile platforms, ranging from handheld devices, mobile robots, and drones to automobiles, aircraft, and ships, require small, light, cost-effective, and longer operating energy systems to meet more aggressive mission profiles [1]-[3]. At the same time, most of these mobile platforms are moving toward more electrification, i.e., electrified-mobility (E-Mobility), if not fully there already. E-Mobility, herein, refers to more electrification of energy conversion systems in mobile platforms. E-Mobility opens new opportunities to meet the required energy system objectives, while also presenting new challenges.

“…Although the load current is linear, non-linear loads of other users cause distortion in AC line voltage. Therefore, efficiency and power factor correction (PFC) has become more important subject for power converters [1]. In fact, it is desirable that the output voltage is obtained at the desired value without causing distortion of the input current.…”

A comparison of fuzzy self-tuning (FST), sliding mode control (SMC) and conventional proportional-integral (PI) control methods is performed under unbalanced grid conditions using a bridgeless power factor correction (PFC) converter. The bridgeless PFC converter operates the correction of AC line current to obtain a DC output voltage without full bridge rectifier based on these control methods. These control methods generate the duty cycles to provide higher unity power factor and lower total harmonic distortion of input current, even if AC line voltage is distorted. This study focuses on the performance analysis of FST and SMC methods adaptation to the input current for the bridgeless PFC converter and comparing with the conventional PI controller. Although the SMC method is only used in the current control loop, the FST method is used in both current and voltage control loops for eliminating harmonics of input current and regulating of output voltage. The performance of control methods is evaluated with a TMS320F2812 digital signal processor. The simulation and experimental results are compatible with the limits for harmonic current emissions, IEC 61000-3-2 and show that the FST and SMC are better than the conventional PI control method and FST is superior to the SMC.

A dynamic voltage compensator (DVC) technique is presented for the minimizing of the capacitance value of the interleaved power factor corrected (PFC) boost converter for the battery charger in electric vehicles. This technique is based on eliminating the ripple on the capacitor by creating a voltage in the opposite direction as well as the amount of ripple on the capacitor. With the proposed method, the capacitance value is reduced by approximately five times. Reducing the size of the capacitor also provides the use of film-capacitors with a longer life. The other contribution of this study is designing a faster and more stable fully-digital control system, instead of the commonly used analogue controller of interleaved PFC boost converter. A 3.3 kW interleaved PFC boost converter is designed to verify the effect of the designed dynamic voltage compensator and digital controller.
