RECTIFIER DRIVE Russian patent published in 2009 - IPC H02P6/00 H02P6/06 H02P6/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in actuating systems of different mechanisms with a wide range of speed regulation. An electric actuator contains an electric motor, a device for generating a digital speed signals, code-to-pulse-duration modulation converter, commutator, device for setting direction of rotation, position sensor, device for converting position feedback signal into code, device for determining position errors and device for determining speed errors, module selection device and a speed scanner, made from two adders, integrator, module selection device, functional generator and multiplier. The signal speed scanner generates an evaluation signal, used in the electric actuator as feedback. Presence of a module selecting device and functional generator in the scanner allows for readjustment of filtering properties of the scanner depending on the value of digital speed signal, eliminating interference in the device for generating digital speed signal, which leads to improvement of quality of the electric actuator properties in a wide range of processing given speed values.

EFFECT: improved dynamic properties, increased stability and reduced speed fluctuation in a wide range of processing given speed values.
