The proposal of high-frequency link inverter utilizing space vector modulation (SVM) is given in (Jin et al., 2023) aimed to alleviate the current stress on cycloconverter switches, despite the operation of semiconductor switches under hard switching conditions.
In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
The steady state waveforms for the conventional high frequency link inverter when operated under Unipolar modulation are presented in Figures 10E, F. The transient behaviour of the proposed inverter is analysed from full-load to no-load and no-load to full-load conditions verified using the simulation results.
High Frequency-Link (HFL) Inverters have been employed to integrate renewable energy sources into utility grids and electric vehicles. The soft-switching range of High-Frequency Link Inverters (HFLI) is increased using auxiliary inductors and capacitors.
