Inventor: MOON GUN WOO
IPC: H01F17/00
Filed: 2021-05-26
Abstract: Disclosed are a new transformer structure and winding layout structure capable of reducing common mode noise generated in a planar transformer. A converter according to one embodiment is configured by connecting primary sides of two half-bridge LLC high-resonant converters in parallel and connecting the secondary sides in series. The converter can be used in medium-high power applications on the basis of a full-bridge structure of the primary side. Each transformer has one terminal connected to a static-point, at which a dv/dt characteristic is zero. Therefore, a primary winding layer has the same dv/dt characteristic as that of a secondary winding layer. Since the primary and secondary layers having the same dv/dt characteristic are connected adjacently, a common mode current generated from the planar transformer can be greatly reduced. As a result, the converter can achieve high power density by reducing the size of an EMI filter.

Filed: 2021-06-17
Abstract: The present invention relates to a low-voltage torch igniter and a method for igniting a torch with a low voltage, which do not apply power to two electrodes in a contact state, but apply power to the two electrodes with the gap between the two electrodes apart, and bring the two electrodes into contact with each other for a while to ignite a torch, not to maintain a short-circuit state, thereby increasing stability and completing the ignition with a low voltage. The method can generate an arc without using a high voltage used in an existing ignition circuit, thereby lowering the possibility of destruction of a torch insulator and reducing an electrical safety burden on users. The method can bring the two electrodes into contact with each other for a short period of time and separate the two electrode from each other, so that the torch can be ignited even when the amount of conducting power is low, thereby reducing a physical burden on the electrodes and increasing durability.
