    Abstract: A thyristor type control circuit for an electric traction motor for a road vehicle includes a thyristor chopper circuit controlling the average current through the armature and series field winding of the motor. The control circuit includes various switch arrangements for switching the armature connections for forward motoring, reverse motoring and electrical braking, but there is a current threshold detector circuit which prevents operation of these switch arrangements when the armature current exceeds a predetermined value. When braking is initiated, therefore, the current flowing is low and since the field winding is in series braking effort cannot build up. The invention provides a contact which connects the field winding to a d.c. supply while the armature current is below the threshold level during braking.

    Abstract: A power supply for realistically controlling a model railroad engine. For engine acceleration, the power supply provides an output signal having a linear ramp with pulses superimposed thereon. For constant speed operation, the supply produces a constant output voltage. For deceleration, the power supply produces a decreasing linear ramp signal with pulses superimposed thereon. Adjustment circuitry is provided for modifying the output waveshape so that realistic control can be achieved for different model engines having different operating characteristics.

    Abstract: The operation of a mechatronic system with a power converter is advantageously and flexibly improved with regard to electromagnetic interference emission and acoustics. A regulation of the instantaneous switching frequency is proposed, with the natural variation of the switching frequency of the delta-sigma PWM in the cycle of the fundamental voltage being taken into account, which can achieve advantages in terms of EMC, acoustics and switching losses. The regulation of the instantaneous switching frequency in particular creates a possibility of generating a specific, calibratable noise with the underlying drive. It can be used to generate a brand-specific, recognizable noise of a vehicle and also to meet normative requirements for the acoustic perceptibility of purely electric vehicles (BEV).
