Latest Patents

Ronald E. Ross holds a patent for a Pulse-modulated servo amplifier. This invention is designed for d-c servo motors and converts the error signal into pulses that are amplified in a saturating amplifier to drive the motor. The unique feature of this amplifier is that both the duty cycle and the repetition rate of the pulses vary with the error signal. At large error signals, the duty cycle is 100 percent, indicating a 'full on' state. Conversely, at small error signals, the duty cycle is low, and the pulses are spaced far apart. As the system approaches balance, the pulses become shorter and less frequent, resulting in a gradual slowdown of the motor. The circuit includes a signal integrator that drives two comparators, one for positive signals and the other for negative. The integrator generates a ramp voltage in the opposite direction of its input polarity and is reset automatically by reset pulses of controlled and variable length when a comparator set point is reached. This innovative design ensures that reducing the gain does not widen the dead band but only increases the time required for rebalance. The dead band is tightly controlled compared to prior systems. Additionally, a novel overload shutdown circuit cuts off the input to the power amplifiers when a large, off-scale input signal occurs for an extended period.
