The high voltage side part includes a first base seat, a first isolator seat having a plurality of isolator grooves, and a plurality of coil sets. The first isolator seat has one end connect to the first base seat and another end with a positioning groove. The plurality of coil sets are wound around the first isolator seat, and are positioned in the plurality of isolator grooves. The low voltage side part includes a second base seat, a second isolator seat, and a plurality of sheet bodies. The second isolator seat has one end connected to the second base seat and another end defining a central column. The central column is positioned in the positioning groove. Each sheet body possesses an opening for containing the central column. The sheet bodies are mutually laminated and interlaced on the central column.

Abstract: A laminar transformer having double-face secondary winding includes a primary winding part and a secondary winding part. The primary winding part further includes an isolating body seat and a plurality of coil sets. The secondary winding part further includes two plate-body set, each being positioned in the containing channel has a plurality of plate bodies and a plurality of insulating bodies. Each of the plate bodies has an opening for containing the central column and a guided channel that being positioned on a side of the opening has on both side thereof a pole lead respectively. The insulating bodies being a ring-shaped structure and being positioned in-between the plate bodies has a through hole for containing the central column. The plurality of plate bodies are laminated alternately and positioned in the central column making each of the plate-body sets form the one with four pole leads.

Abstract: A super high power transformer includes a base, a plurality of plate bodies, and a plurality of isolating bodies. The base further includes a main core part, a plurality of opening slots, and a plurality of side wing parts. The main core part has a penetrating hole at the center thereof. Each of the plate bodies has an open hole for slipping on the main core part and a guided slot that has a pole lead on both sides thereof. Each of the isolating bodies has a through hole for slipping on the main core part and a guided slot. There is also a pole lead positioned on both sides of the guided slot. To be slipped on the main core part, the plurality of plate bodies and the insulating bodies are alternately stacked up with the plate bodies staggering in turning a 90-degree angle apart sequentially.

Abstract: A building-block-combined-type high power transformer includes a first iron core body contacting a second iron core body, a plurality of plate bodies, and a plurality of isolating bodies. The first iron core body and the second iron core body have a first side wing part and a second side wing part respectively at both sides thereof. Both the first side wing part and the second side wing part respectively have a first open channel and a second open channel formed there between. Each of the plate bodies is positioned in both the first open channel and second open channel. Each of the isolating bodies is positioned between first plate bodies and second plate bodies of the plurality of plate bodies. The first side wing part and the second side wing part are inserted through an open hole of corresponding plate bodies and a through hole of corresponding isolating bodies.

The plurality of coil sets are wound around the first isolator seat, are corresponding to and are positioned in the plurality of isolator grooves. The low voltage side part further includes a second base seat, a second isolator seat having a central column, and a plurality of sheet body. The second isolator seat has its one end that is connected to the second base seat. The central column has its one end surface position at the positioning groove. Each of the sheet body possesses an opening for containing the central column.

Abstract: A constant frequency power supply applied in an exchange-type circuit having a primary winding and a secondary winding includes a first core, a second core, a first bobbin, and a second bobbin. The first core and the second core being disposed in opposite position have a first protruded body and a second protruded body respectively. The first bobbin being positioned on the first protruded body and having a first set of coils wound around thereof is electrically connected to a first set of connecting pins of the primary winding The second bobbin being positioned on the second protruded body and having a second set of coils wound around thereof is electrically connected to the second set of connecting pins of the secondary winding. The first bobbin further includes a slip opening that is capable of slipping on the second bobbin.
