Power electronics is an engineering discipline focused on the conversion, conditioning and control of electric power by means of power semiconductor switching devices, passive energy-storage components and associated control circuitry ^[1]. It implements controlled mutual conversion between alternating-current and direct-current electric energy forms, as well as adjustment of voltage magnitude, current amplitude and operating frequency for power-level energy flow ^[2]. It targets high-energy-flow power processing applications, and is conceptually distinct from small-signal analogue electronics which are primarily designed for information signal processing and communication rather than bulk energy conversion. The field encompasses converter topologies, semiconductor device physics, control algorithms, electromagnetic design and thermal management aspects of power conversion systems ^[3].
