US 2026/0218936 A1 · AIR CONDITIONING SYSTEM INCLUDING DUAL MODE INVERTER CONTROL

Abstract

An air conditioning system includes an inverter and a power factor correction circuit in signal communication with the inverter. The inverter converts a DC voltage delivered from a DC voltage supply into an AC voltage. The power factor correction circuit delivers an AC line voltage across an AC voltage line based on the AC voltage and outputs an AC line voltage signal that is indicative of the AC line voltage. An inverter controller receives a feedback of the AC voltage from the inverter and receives an AC line signal from the PFC circuit. The inverter control selectively operates in a first mode to control the inverter based on the AC line voltage signal and a second mode to control the inverter based on the feedback of the inverter output.
