IPC: H02P7/29
Filed: 1983-03-14
Abstract: PURPOSE:To simplify the construction and to largely reduce a commutation failure of a controller for an electric rolling stock by employing a chopper control system and constantly controlling acceleration due to the chopper control of an open loop. CONSTITUTION:The pattern voltage of a pattern voltage generator 1 is compared by a comparator 3 with the sawtooth wave voltage of a sawtooth wave generator 2, a timing of ON and OFF of a chopper is formed, this output is inputted to a pulse generator to convert the output into a pulse and to feed it as trigger pulse of ON and OFF to the chopper. The generator 1 generates a pattern to become a target, and mean a voltage similar to this pattern voltage is applied to a motor. The generator 2 decides the chopper period of shorten the period as short as possible by considering the performance of an SCR chopper.
