Cover Story: CSIs (Current Source Inverters) are promising techniques for EV charging and electrosurgical generators, with advantages in respect of eliminating system failure caused by capacitors and inherent short-circuit protection capabilities. However, two essential questions remain that prohibit CSIs’ promotion and application: (1). The output characteristics and parameter design procedure are unclear; (2). The power efficiency analysis is less specific, especially the effect of using SiC devices on improving efficiency. This paper describes a CSI topology and analyzes the operation condition by proposing two kinds of models. The output waveforms and the parameter design procedure are derived. The power efficiencies of Si-based and SiC-based CSI are calculated and compared. Ultimately, a set of simulations and experiments demonstrate the theoretical analysis and calculations.
