The frequency conversion power supply has no radiation interference and low conduction interference, which can meet the requirements of laboratory equipment for power supply. However, the frequency converter has low radiation interference and strong conduction interference, and the laboratory equipment cannot work normally.
The variable frequency power supply is allowed to output single-phase and three-phase. When three-phase output, it can withstand 100% unbalanced load, while the inverter has only three-phase output, and its ability to withstand unbalanced load when three-phase is poor;
The variable frequency power supply adopts IGBT/SPWM control mode, while the inverter adopts IGBT/V/F control mode.
