	The NSLS-II booster is a full-energy synchrotron with the range from 200 MeV up to 3 GeV. The ramping cycle is 1 second. A set of electronics developed in BNL fro the NSLS-II project was modified for the booster Power Supplies (PSs) control. The set includes Power Supply Interface which is located close to a power supply and a Power Supply Controller (PSC) which is connected to EPICS IOC running in a front-end computer via 100 Mbit Ethernet. A table of 10k setpoints uploaded to the memory of PSC defines a behavior of a PS in the machine cycle. A special software is implemented in IOC to provide a smooth shape of the ramping waveform in the case of the waveform change. A Ramp Manager (RM) high level application is developed in python to provide an easy change, compare, copy the ramping waveforms, and upload them to process variables. The RM provides check of a waveform derivative, manual adjusting of the waveform in graph and text format, and includes all specific features of the booster PSs control. This paper describes software for the booster ramp handling.
