摘要： An isolated fly-buck converter provided for converting an input voltage (Vin) to an output voltage (VS) comprises (i) on a primary side, a primary winding (X1) and a non-isolated buck (CP) connected in series, and a pair of switches (Q1, Q2), wherein the switches are switchable between a forward phase, in which the primary winding and the non-isolated buck are connected to the input voltage, and a fly-buck phase, in which the primary winding and the non-isolated buck are disconnected from the input voltage and are connected to one another in a closed circuit; and (ii) on a secondary side, a secondary winding (X2) coupled to the primary winding, and a first capacitive element (CS) connected over the secondary winding and a first rectifying element (D1) connected to the secondary winding to prevent current from being flown through the secondary winding during the forward phase, wherein the output voltage is achieved as the voltage over the first capacitive element. A supplementary circuitry is provided at the secondary side by aid of which the input voltage can be measured on the secondary side, the supplementary circuitry comprising a second capacitive element (CF) and a second rectifying element (D2) connected in series, wherein the supplementary circuitry is connected over the second wiring such that the second rectifying element prevents current from being flown through the supplementary circuitry during the fly-buck phase, wherein the sum of the voltage over the second capacitive element and the output voltage is indicative of the input voltage.

摘要： An isolated DC/DC converter (3) includes a full-bridge type switching circuit. A primary winding of a transformer (6) and a resonance reactor (5) are connected in series to each other. Another end of each of the primary winding and the resonance reactor (5) is connected to one of middle points between switching elements. First and second surge suppression diodes (D5 and D6) are provided to a node between the resonance reactor (5) and the primary winding of the transformer (6) and between a positive side and a negative side of a capacitor (4). This configuration suppresses a surge voltage applied to the transformer by releasing surge energy of the resonance reactor (5) caused by a recovery of rectifying diodes (D1 to D4) on a secondary side of the transformer (6) via the surge suppression diodes (D5 and D6).

The first switching element (140) is pulsed at a defined switching frequency and has an on -time operative to provide a defined charge level on the primary winding (110). The second switching element (130) is pulsed at the same switching frequency and in synchronization with the first switching element (140), such that an on- time of the second switching element (130) is extended with respect to the on- time of the first switching element (140). An LED lighting unit comprises a first printed circuit board formed with a pre-defined shape for attachment to a socket on which the resonant fly-back power converter is mounted, at least one second printed circuit board including at least one LED lighting module, and an attachment mechanism for physically and electrically connecting the first and second printed circuit board.

摘要： Der Gleichstromsteller ist mit einem Eingang, an dem eine Eingangsspannung anliegt, mit Schaltern (S1,S2) und wenigstens einer Induktivität (5) versehen. Am Ausgang des Gleichstromstellers liegt eine Ausgangsspannung an. Ein Transformator (9) des Gleichstromstellers hat Wicklungen (6,7), die gegensinnig zueinander gewickelt und in Reihe zu den Schaltern (S1,S2) und zur Induktivität liegen. Die Schalter (S1,S2) sind abwechselnd, aber während einer Überlappungszeit auch gleichzeitig geschlossen. Wenn der durch die Induktivität (5) fließende Strom einen bestimmten Stromwert unterschreitet, werden beide Schalter (S1,S2) geschlossen, so dass der durch die Induktivität (5) fließende Strom wieder zunimmt.
