The rectifier 44 can be synchronous rectifier composed of four metal-oxide-semiconductor field-effect transistors (MOSFETs). Each of the power-converting units 41a˜41d further includes a electrically conductive plate 48 placed on the base portion 420, and the electrically conductive plate 48 and the rectifier 44 are placed on the same surface. The filter 46 is, for example, choke.
The surface of the power-converting unit 41b placed with the filter 46 faces the surface of the power-converting unit 41c placed with the filter 46, which means that the filters 46 of the two power-converting units 41b and 41c close to the second channel 109 face each other, and the length of two filters 46 aforementioned is substantially equal to the width of the second channel 109.
Moreover, the surface of the circuit board 42 of the power-converting unit 41a placed with the rectifier 44 faces the surface of the circuit board 42 of the power-converting unit 41b placed with the rectifier 44. In the other words, two power-converting units 41a and 41b (or 41c and 41d) arranged at the same side of the second channel 109 face each other. In such manner, the integrated power-converting module is compact since the power-converting units 41a˜41d are tightly arranged.
The integrated power-converting module of the present invention having circuit diagram shown in FIG. 1 and arrangement shown in FIG. 2 and FIG. 6, which has advantage of compact and eddy current loss and switching loss can be effectively reduced.
The integrated power-converting module can be mounted on a circuit main board, in the other words, the circuit main board is disposed below the integrated power-converting module. The fixing members 13 is inserted into the circuit main board, so that the integrated power-converting module can stand on the circuit main board to prevent the integrated power-converting module from tilt caused by heavy weight. It should be noted that if the integrated power-converting module includes both the fixing members 13 and the electrically conductive terminals 12, the electrically conductive terminals 12 can be disposed at the bottom of the receiving portions 104a˜104d, and the primary coil 30 can be connected to the electrically connected terminals 12 and electrically connected to the circuit main board via the electrically connected terminals 12. The fixing members 13 are disposed at the bottom of the receiving portions 104a˜104d where the electrically conductive terminal is not disposed, such that the integrated power-converting module can stand firmly on the circuit main board. If the integrated power-converting module only includes the fixing members 13, the fixing members 13 are disposed at the bottom of the receiving portions 104a˜104d, and the primary coil 20 wound on the bobbin 10 is directly connected to the circuit main board (by fly line connection). In the practical application, the arrangement of the electrically connective terminals 12 and the mixing member 13 can be adjusted based on the different situations.
The integrated power-converting module of the present invention for outputting multiple direct current electric powers integrates secondary windings (the copper foil or electrically conductive sheet 43 formed on the extending portions 422), the rectifier 44, and the filter 46 into one circuit board 42, which is assembled with the bobbin 10 by inserting the extending portions 422 into the receiving portions 104a˜104d respectively. Thus it is compact and easily to manufacture and assemble.
Although the present invention has been described with reference to the foregoing preferred embodiment, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
