Latest Patents

Clark's latest patents include an innovative electrical braking transitioning control system. This system provides smooth transitioning between regenerative and plug braking of a DC electric motor. It utilizes a low ohmic value resistance path to maintain motor torque during the transitioning phase. During the initiation of electrical braking, a similar low ohmic resistance path momentarily connects the motor to a power source. This connection establishes the proper magnetic flux in the motor, enabling effective regenerative braking. Both resistance paths are disabled during motoring and braking modes to minimize power loss.

Another significant patent by Clark is a method and apparatus for plug sensing in DC electric motors. This invention comprises logic circuitry that responds to a direction change command to initiate a plugging signal. Additional logic circuitry maintains the plugging signal based on the percentage on time of a variable time ratio switch supplying power to the motor. Inhibit circuitry is also included to override the plugging signal under operator-selected conditions.
