摘要： The invention relates to a method for driving a gas discharge lamp and relates to a lamp driver circuit for driving a gas discharge lamp in accordance with said method. The method comprises supplying a current to the gas discharge lamp, reversing the direction of the current supplied to the gas discharge lamp and, substantially simultaneously, generating a relatively high voltage. The generated high voltage serves to prevent a series of re-ignitions of the gas discharge lamp that may lead to visible flickering of the gas discharge lamp or to extinction of the gas discharge lamp.

摘要： A method of controlling an inverter (4) of a gas discharge lamp circuit. The inverter comprises two branches, each having a first semiconductor switch (32, 36) in series with a second semiconductor switch (34, 38) and having a connection node (40, 44), which is connected to a respective output terminal (42, 46) of the inverter. The first and second switches are connected to a first input terminal (16) and to a second input terminal (18) of the inverter, respectively. Each switch has an intrinsic or externally connected antiparallel diode(52-56). The switches of the branches are controlled by a controller in an alternating and cross-like manner to conduct and to not conduct. Controlling of switches is delayed by a first delay time per branch and by a second delay time between branches.

More particularly, the present invention is directed to a resonant-type power converter circuit which comprises an in- terphase transformer (406) connected in series to at least one series resonant tank circuit (403a and 403a' or 403b and 403b') at the output of two DC/AC power inverter stages (402a+b) supplying a multi-primary winding high-voltage transformer (404), wherein said interphase transformer (406) serves for removing the difference (DI) in the resonant output currents ( I 1 and I 2 ) of the DC/AC power inverter stages (402a+b). Furthermore, the present invention is dedicated to a control method which assures that the interphase transformer (406) is not saturated. This control method ensures zero current operation and provides for that input power losses can be minimized.
