1. IntroductionSolar energy is widely used in the sustainable and environment-friendly power generation field [1]. Due to the simple structure and mature control technology, a voltage source inverter (VSI) is commonly adopted in the photovoltaic (PV) grid-connected system [2]. However, the VSI is a buck inverter, which requires the DC input voltage to be higher than the peak of the AC output voltage [3].

1. IntroductionInverters can be categorized as voltage source inverters (VSI) [1] and current source inverters (CSI) [2] according to the characteristics of input power supplies. Some unique advantages of CSIs have been discovered [3], such as their boost capacity, inherent short-circuit protection capacity, and AC filtering structure. CSI, therefore, has potential applications [4] in the solar photovoltaic industry, wind energy power generation, motor drive systems, and HVDC transmission systems.
