摘要： A transformer includes a bobbin unit, a primary winding, a secondary winding, and a core unit. The bobbin unit has a first winding portion and a second winding portion. The primary winding is wound around the first winding portion of the bobbin unit. The secondary winding is wound around the second winding portion of the bobbin unit, and is coupled electromagnetically to the primary winding. The core unit is mounted to the bobbin unit, and includes a first core part, and a second core part that forms a magnetic circuit path with the first core part. The first core part is movable relative to the second core part from a tunable position to an assembled position for varying a size of an effective magnetic flux region defined between the first core part and the second core part.

摘要： A lamp driving circuit includes a step-up transformer, a detector, and a controller. The step-up transformer includes a primary winding, and a secondary winding configured to cooperate with a discharge lamp to form a tank circuit that generates a tank current. The detector is adapted for detecting current magnitude of current flowing through the discharge lamp, and outputs a detecting signal corresponding to the current magnitude. The controller receives the detecting signal from the detector, and generates a drive signal for driving the step-up transformer. The controller includes a capacitor, and configures a waveform of the drive signal by controlling charging of the capacitor based on a calculation value that corresponds to a frequency of the drive signal, a start-setting value, and a difference between the detecting signal and a current-setting signal.

摘要： A current balancing circuit for first and second lamp sets includes a step-up transformer and a current balancer. The step-up transformer is adapted to be coupled to a power supply for receiving an alternating-current source power, and for generating a drive signal by varying magnitude of the alternating-current source power. The step-up transformer is further adapted to be coupled to the first and second lamp sets for providing the drive signal thereto. The current balancer includes first and second shunt transformers. Each of the first and second shunt transformers includes primary and secondary windings that correspond to each other in number of turns thereof. The first and second shunt transformers are adapted to be coupled to corresponding discharge lamps of the first lamp set. The current balancer is adapted to mirror current flowing through the first and second shunt transformers to the second lamp set.

摘要： A transformer includes a core unit that includes an elongated first core part extending in a longitudinal direction and having first and second segments, and an E-shaped second core part including a connecting segment that extends in the longitudinal direction, and three extension segments that extend from the connecting segment in a transverse direction. A central one of the extension segments is disposed in contact with the second segment. The second segment has a size in the transverse direction that gradually decreases along the longitudinal direction away from the first segment. The first core part is movable relative to the second core part from a tunable position to an assembled position for adjusting a position of the second segment relative to the central one of the extension segments so as to vary a size of an effective magnetic flux region defined between the first and second core parts.
