Abstract
Power converters, controllers, methods and non-transitory computer readable mediums are presented, in which a processor operates a switching rectifier in a first mode to regulate a DC bus voltage signal using rectifier switching control for motoring rectifier operation when the measured DC bus voltage value is less than or equal to a first threshold value, operates the switching rectifier in a second mode to regulate the DC bus voltage signal using rectifier switching control for regenerative rectifier operation when the measured DC bus voltage value is greater than the first threshold value and less than or equal to a higher second threshold value, and operates an inverter in a third mode to regulate the DC bus voltage signal using inverter acceleration/deceleration control when the measured DC bus voltage value is greater than the second threshold value.
