摘要： A driving method for a fluorescent lamp is provided. A driving signal for driving the fluorescent lamp is generated, and an operating current of the fluorescent lamp is detected. The frequency of the driving signal is adjusted when the operating current of the fluorescent lamp reaches a first predetermined value. Besides, whether or not the operating current of the fluorescent lamp reaches a second predetermined value is detected in order to decide whether to stop generating the driving signal or not, wherein the second predetermined value is greater than the first predetermined value.

摘要： For having magnitudes of all currents for supplying for all passive elements in a same product be equal, a current balancing module, which has balancing transformers as more as approximately half an amount of all the passive elements, is provided for meeting such requirements. The provided current balancing module is for solving defects caused by complicated designs and increased volumes caused by an increased number of balancing transformers. Each current path in the current balancing module flows through two mutual-corresponding passive elements and at least one balancing transformer. All the current paths have a same magnitude in current with the aid of a pair of sinusoidal waves having same magnitudes and opposite poles, and the aid of all the balancing transformers having a same number of turns.
