The ballast control circuit and control method of the invention is advantageous by allowing the OFF time of the main switch of the ballast circuit to be fixed in order to prevent the transformer of the ballast circuit from being saturated when the gas discharge lamp is ignited and has a very low impedance, and allowing the OFF time of the main switch to be flexibly adapted when the gas discharge lamp is warmed up and its impedance has risen up to a certain value. The inventive ballast control circuit is configured to proceed with the switching of the main switch according to a lamp status signal indicative of the status of the lamp.

    摘要: A method for starting-up a motor having multiple stator windings and a rotor contains first providing current to two of the windings to excite a predefined phase and allowing one of the windings floating, Then, the back electromotive force (BEMF) induced in the floating winding is monitored. If a zero crossing of BEMF occurs in the floating winding within the maximum startup time, then it commutates to the next phase, which is adjacent to the first initial phase in the predetermined sequence of excitation phases. If no zero crossing of BEMF occurs in the floating winding within the maximum startup time, then it commutates to the next phase, which is functionally shifted by two phase-intervals from the predefined phase.
