Abstract—This paper presents a closed-loop controller design approach for a single-phase (1 ) pulse-width modulated (PWM) high frequency (HF) AC inverter, supplying the non-linear load for space application. Control challenges in HF inverter are highlighted compared with 50/60 Hz conventional. . The High-Frequency Inverter is mainly used today in uninterruptible power supply systems, AC motor drives, induction heating and renewable energy source systems. The simplest form of an inverter is the bridge-type, where a power bridge is controlled according to the sinusoidal pulse-width. . This technical note introduces the working principle of an Active Front End (AFE) and presents an implementation example built with the TPI 8032 programmable inverter. The control scheme executes fraction order PID (FOPID). The design supports two modes of operation for the inverter: a voltage source mode using an output LC filter, and a grid connected mode with an output LCL filter. High-efficiency, low THD. .
