Abstract: A transformer including first coil unit and second unit, wherein one or more coils are wound on the bobbin of insulating material in at least one of the first coil unit and the second unit, and wherein the bobbin is formed with at least one partitioning flange for partitioning a coil winding surface of the bobbin into two winding surfaces along the longitudinal direction of the bobbin, is disclosed.

Abstract: A high precision DC/DC resonant converter with a wide load range includes a first switch leg having one end connected to an anode terminal of a DC power source and the other connected to a cathode terminal of the DC power source to independently operate at a switching frequency used in an application of an output voltage for no load or a light load equal to or less than a rated load; and one or more second switch legs having one end connected to the anode terminal of the DC power source and the other end connected to the cathode terminal of the DC power source to operate at a switching frequency for the rated load or a frequency equal to or less than the switching frequency used in the application of the output voltage for no load or the light load that the first switch leg takes charge of.

Abstract: An active voltage drop control-type pulse power generator includes power stages, a power inverter, a power loop, a control inverter, a control loop, and a compensation unit. The power stages include power cells connected in series. Each power cell includes a switch and a capacitor connected in series, a driver for driving the switch, a bypass diode connected to both ends of the switch, and a rectifying diode connected to both ends of the capacitor. The power inverter charges the capacitor via the power loop and the rectifying diode inside each power cell. The control inverter provides a control signal for the switch via the control loop and the driver inside each power cell. The compensation unit is connected to one of the power cells and generates a compensation voltage for compensating for a voltage drop at a load according to a voltage detected in real-time from the power cell.
