Existing electric vehicles (EV) in the market require two separate power processors for propulsion and on-board wired charging operations. EV with wireless charging feature requires an additional power processing unit to be fitted with the vehicle and thus requires three separate power processors. Existing integrated chargers support any two of these operating modes (i.e., either propulsion and wired charging or wired and wireless charging) out of three required operating modes. In order to optimize size, volume, and weight along with the cost, a novel reconfigurable power processor (RPP) is presented in this article that replaces the need of three separate power processors in an EV. The proposed power processor restructures itself as three different power electronic topologies during three modes of operations. For wireless charging mode, a new converter topology is also proposed in this article for the transmitting unit at the primary side. During both wired and wireless charging methods, the proposed solution draws power from a single-phase ac supply to optimally charge the EV battery pack with CC-CV algorithm and simultaneously maintaining near unity power factor (PF) at the grid side. The proposed idea is validated in the laboratory environment with an experimental set up consisting of a 24 V, 400 W BLDC motor and a 24 V, 30 Ah battery.

In 1881, Morton found that a high-frequency (100-kHz) current could pass through the human body without inducing pain, spasm, or burn [1]. This work was followed in 1891 by d’Arsonval who noted similar observations at a frequency of 10 kHz and noted that the current directly influenced body temperature, oxygen absorption, and carbon dioxide elimination, increasing each as the current passed through the body [2], [3]. In 1897, Nagelschmidt identified [1] that patients with articular and circulatory ailments benefited from the application of electrical currents, which led to him proposing the term diathermy to describe the heating effect discovered in [2]. In 1900, Rivere, while treating an insomniac patient with electricity observed that a spark arcing from an electrode coagulated an area of his skin and subsequently, used this arcing current to treat a carcinomatous ulcer on the hand of a patient. This event has been cited as the first true use of electricity in surgery [1], [3], [4], [5]. Notwithstanding, many credit the invention of electrosurgery devices in 1926 to William Bovie [6].

The micro-modular multilevel converter ($mu $ MMC) concept proposes a benchtop-scale, low-voltage, open-source, and affordable hardware prototype of a modular multilevel converter (MMC) intended for research and teaching applications. The $mu $ MMC ($mu $ originates from its rating being approximately one millionth of usual transmission-scale MMCs) aims to provide a solution to break the barrier from theory to practice, thanks to its all-integrated eight full-bridge (FB) submodules (SM) in a $10times 10$ cm printed circuit board (PCB) with a local microcontroller able to communicate with an external master controller. The electronics is rated for a 30 V dc bus voltage as typically found in traditional lab power supplies, providing both convenience and safety. This structure allows a lot of flexibility in terms of testing converter topology and control architectures. This article details the setup process of the $mu $ MMC into a 3-phase inverter to demonstrate its versatility and potential as a teaching and research tool.
