Abstract
Purpose. Development of methods of experimental determination of action coordination characteristics of semiconductor and mechanical switching elements in systems of hybrid commutation of bistable actuators coils taking into account contact bounce of mechanical switching elements. Consideration of the application possibility of interface relay as mechanical switches, and the definition of the duration of the intervals to ensure coordination of the relay operation with semiconductor switches. Methodology. Experimental determination of the time intervals between the moments of switching transistor which controls the relay coil, and power transistor when the switching on and off operations using a hybrid switching device are performed; statistical processing of experimental results. Results. The durations of the time intervals between the moments of switching of semiconductor and mechanical switching elements in systems of actuator coils hybrid commutation are experimentally determined. A way of a significant reduction of the duration of the indicated time intervals is considered and experimentally confirmed. Originality. The scheme of the power circuit of the control system with hybrid commutation of the actuator coil circuit, which differs from the known schemes that the only semiconductor switching element performs functions of the current switching on and off, and electromechanical relay contact elements act as a router interconnecting electrical circuits during dead times. Practical value. The use of hybrid switches instead of switches with semiconductor switches will significantly reduce the cost of the actuators control system, as well as reduce their sizes.
