摘要： A propulsion system for an unmanned underwater vehicle includes a turbine engine having a rotational output, an electrical generator mechanically connected to the rotational output and electrically connected to an Alternating Current (AC) power bus. A magnitude of an AC output of the electrical generator is independent of rotational speed of the rotational input. An electrical motor connected to the AC power bus, and includes a mechanical output.

摘要： A method for controlling a switch that controls a power supply line of an electric motor from an alternating voltage source, including determination of a switch closing instant (tf) starting from a measurement of the derivative of the current carried on the power supply line. A starter system and a computer program product are capable of using this method.

摘要： The present disclosure provides a single phase motor driving circuit which includes a stator winding, a control unit, a controllable bidirectional AC switch, and two power input terminals configured to connect an AC power source. The stator winding includes a first winding and a second winding. The parallel-connected first winding and second winding and the controllable bidirectional AC switch are connected in series between the two power input terminals. The control unit is connected to a control electrode of the controllable bidirectional AC switch, to control the controllable bidirectional AC switch to be switched on and off. The present disclosure further provides a driving method for the single phase motor driving circuit. The single phase motor driving circuit and the driving method thereof has better reliability while ensuring sufficient starting torque.
