High-Frequency Topology
High-frequency UPS designs use IGBT switching at frequencies far above mains (typically 10–20 kHz or higher) to regulate output via a small filter inductor instead of a heavy 50/60 Hz output transformer. The Pure Line page on Standby Systems names “high-frequency technologies” as the basis for delivering clean filtered sine-wave inverter output. The trade-off versus transformer-based designs is loss of galvanic isolation, which matters in some medical and industrial regimes — see Galvanic Isolation.
