摘要： An inductive load drive device is disclosed comprising: a monitor circuit that inputs the drive-side terminal voltage of an inductive load (ZL) and, when a drive current of the inductive load (ZL) is cut off or rapidly decreased, outputs an operation confirmation signal by detecting a surge current generated by self-induction of the inductive load (ZL), wherein the monitor circuit outputs a confirmation signal that detects a surge produced when a large current flowing in the load due to high voltage applied in an initial period of drive of the load (ZL) is rapidly decreased, wherein in order to prevent confusion of the surge with a surge produced when the load drive is terminated, the operating confirmation signal is masked by using a control signal indicative of the termination of drive of the inductive load.

摘要： A transformer (201) includes a push-pull winding wherein each side is divided at its centerpoint and leads are brought out for switching devices (204) or rectifiers (205) so that leads from the source voltage and to the loads are separate from the switching devices and rectifiers which may be located for optimal circuit topology. The winding may be of coaxial wire for improved performance and floating capacitors (208) or floating snubbers (206) may cross couple the terminals where the switches (204) and rectifiers (205) are connected.

摘要： A bidirectional power converter comprising a number of flyback converter units (10, 12) connected in parallel, each converter unit having a controller (22, 22a) and being adapted to accumulate power from a primary side during an ON time of the unit and to deliver the accumulated power to a secondary side during an OFF time, the primary and secondary sides being interchangeable in accordance with the direction of power conversion, the controller (22, 22a) being configured to operate at a boundary between a discontinuous conduction mode and a continuous conduction mode and to perform valley switching when switching from OFF to ON, characterized in that one (10) of the converter units is configured to operate as a master wherein the controller (22) is adapted to control the length (T_ON) of the ON time in order to feedback-control an overall current output (I) of the converter, and each of the other converter units (12) is configured to operate as a slave wherein the controller (22a) is adapted to control the length (T_ON) of the ON time in order to feedback-control a phase delay (Δφ) of the ON time of the slave relative to the ON time of another one of the converter units.
