                        WAVEFORMS


The tubular axle induction motor programme included the operation of the motor
when fed from a 120º square wave inverter. This memorandum describes an analysis
technique which enables the relationships between inverter voltages and currents to
be determined.

The method described for prediction of the current and voltage waveforms is
original and complete. Good correlation between predicted and measured waveforms
has been achieved. The analysis is independent of stability consideration and thus
can complement stability studies.
