- 18. What is Regenerative Power? Fig a) Normal operation of 3 Phase motor with drive Fig b) Breaking mechanism slows/stops the motor, which generates regenerative power & returned to the input side i.e. to the power supply. In case of UPS as power supply, it shall be capable to feed back the regenerative power to the mains. Liebert RG
- 19. Working Principal Liebert RG Re- generative Load Bypass Input Battery IGBT Rectifier IGBT Inverter Isolation Transformer STSW STSW Mains Input Normal mode In Normal mode, the rectifier derives power from the commercial AC source and converts it into DC power for the inverter and the battery charger. The battery charger keeps the battery in a fully charged and optimum operational condition. The inverter converts the DC power into clean and regulated AC power which is supplied to the critical load (conditioned line). The static switch monitors and ensures that the inverter tracks the bypass supply frequency. This ensures that any automatic transfer to the bypass supply (due to an overload etc.) is frequency synchronised and does not cause interruption to the critical load.
- 20. Working Principal Liebert RG Re- generative Load Bypass Input Battery IGBT Rectifier IGBT Inverter Isolation Transformer STSW STSW Mains Input Dynamic breaking mode When Braking mechanism slows/stops the motor, which generates regenerative power & returned to the input side i.e. to the power supply. In such condition, Liebert RG fed back the regenerative power to the mains via Inverter & Rectifier without causing interruption to the critical load & thus there will be considerable energy savings during regeneration transients.
