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.
