The power supply does not need any alternating current voltage detection circuit. The voltage value of the alternating current voltage is derived by determining the duty cycle of the pulse width modulation signal.

Abstract: A brushless motor control apparatus calculates the number of rotations of an engine based on a cycle of zero-cross points of the phase voltage induced to a sub-coil of a three-phase brushless motor. When the number of rotation of the engine is smaller than the first number of rotations, before it becomes impossible to detect the zero-cross points, the control state of the three-phase brushless motor is changed from the state of phase control by a phase control regulator unit with respect to the AC output voltages to the state of interphase short circuit of motor coils by a short regulator unit.

Abstract: A starting method and system for a motor where the motor may be started as an induction motor by applying a magnetizing current to build flux through the stator, with the field current set at the maximum permissible exciter stator current (i.e., the current that will cause rated no-load current in the main field at the transition speed). The motor stator currents will be maintained at a value that allows the motor to generate sufficient breakaway torque to overcome any stiction. At a specific transition speed or after a period of time, the drive will initiate a transition from induction motor control to synchronous motor control by removing the initial magnetizing current, and a field current is then applied to the motor through the DC exciter. Once this transition is completed, the drive may ramp up to the desired speed demand.

Abstract: An embodiment of the present invention may seek to match the generator and grid voltages before the powerplant machine reaches the grid matching speed during the start-up process. An embodiment of the present invention may provide a predictive algorithm, or the like, to control the acceleration rate of the powerplant machine to target a particular phase angle differential between the powerplant machine and the grid when the powerplant machine reaches the grid matching speed. Here, the phase angle difference may be targeted such that a generator breaker may be closed immediately after the powerplant machine accelerates beyond the grid matching speed. This may avoid the generator experiencing a phase angle differential, which may add to the power transient associated with the generator breaker closure.

Abstract: A voltage raising device that provisionally maintains an operation and function when there is an abnormality provided. If a battery voltage drops when an engine is restarted after an idle stop, the voltage raising device raises the output voltage to a target voltage by using a voltage detecting circuit and a current detecting circuit. If an overcurrent determining circuit detects overcurrent, a switching control circuit reduces the target voltage to perform a control. If overvoltage is output, for example, due to an increased target voltage caused by an internal setting deviation resulting from a failure, an overvoltage detecting circuit outputs a prohibition signal ENV to stop the switching operation. However, as long as the output voltage is not overvoltage, the voltage raising operation is allowed. Therefore, the possibility that the engine can be started at least once without a problem is increased.

Abstract: When a wind velocity sensor detects a wind velocity higher than a predetermined level, a timer device starts a waiting timer function during an operation timer period shorter than the waiting timer period. After the waiting timer period is over, the waiting timer function is switched to an operation timer function, and a switching relay switches a generator to a motor only during an operation timer period. Then, a driving circuit performs a start assisting rotation. After the operation timer period is over, the waiting timer period re-starts. This process is repeated. When during this period, the number of rotations of a rotor monitored by a rotation number measuring device, based on the output voltage Vm of a three-phase conduction coil exceeds a predetermined number of rotations, the charging of a battery by a three-phase generator is started.
