APLYING VARIABLE SPEED DRIVES ON AGENERATOR POWER : John T. StreicherObjective:The intent of this document is to explain some of the issues related to powering a typical AC drive from agenerator source. Some of the information given is theoretical and some data shown comes from actualinstallations. Since each system configuration and performance requirements are unique it is impossibleto give hard and fast numbers that will guarantee satisfactory operation. It is the hope of the author thatthis document will give others a better understanding of the drive / generator system and help thoseresponsible for the installation to make it a successful :There are two basic ways a generator can be used as a power source, stand-by (back up) or permanent(dedicated).

SCR’s (Silicon Controlled Rectifier) or 6 diodes to create a full wave three phase bridge rectifier. For a three phase system, each phase creates 2 pulses resulting in what is called a 6 pulse rectified converter. The converter section is often refered to as the “front end”. The front end converts the 3 phase AC line to a DC voltage which ...
