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 scanning backlight unit (BU) for a matrix display comprises a plurality of light sources (L1, ...,Ln). A driver (2) supplies drive signals (D1, ...,Dn) to the light sources (L1, ...,Ln). A controller (3) controls the driver (2) to separately activate the light sources (L1, ...,Ln) to obtain light-emitting regions (5) being active. A light sensor (4) is associated with a group of at least two of the light sources (L1, ...,Ln) to supply a sensor signal (SES) which indicates a luminance (LU) of the group. The controller (3) reads the sensor signal (SES) at different instants (ts1, ..., tsn) at which mutually different subsets of the light sources (L1, ...,Ln) of the group are active to control the driver (2) to supply power levels to the light sources (L1, ...,Ln) of the group to obtain a luminance (LU1, ...,LUn) of each one of the light sources (L1, ...,Ln) of the group in dependence on the sensor signal (SES).

摘要： The invention relates to an AC/DC converter circuit (100) and a method for converting N≧2 AC supply voltages (U1, U2, U3) into DC voltage. This is achieved by feeding the AC supply voltages to first terminals (a1, a2, a3) of full bridge converters (11, 12, 13), wherein the second terminals (b1, b2, b3) of these rectifiers are coupled to each other. The outputs (d11, d1′, d2, d2′, d3, d3′) of the rectifiers are fed to the DC terminals of intermediate converters (21, 22, 23). The AC terminals (e1, e1′, e2, e2′, e3, e3′) of the intermediate converters are connected to the primary sides of transformers (31, 32, 33), wherein the secondary sides of these transformers are provided to further rectifiers (41, 42, 43). The circuit design allows using MosFETs of limited voltage capability for processing 380 V three-phase AC current, thus achieving a high efficiency.

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 (TdI) per branch and by a second delay time (Td2) between branches.

摘要： The invention relates to a time discrete control of a continuous quantity (I1). In order to achieve a higher resolution of the time discrete control and to avoid an unstable control due to low-frequency effects, an artificial, varying disturbance is introduced to at least one signal involved in the time discrete control. A corresponding control circuit is provided with components (10-14) adapted to perform the time discrete control of the continuous quantity (I1), and in addition with at least one component (20,2 1) adapted to introduce the artificial, varying disturbance to at least one signal in the control circuit.
