DC/DC Converter (DC/DC Converter), as its name implies, regulates the input DC power supply by voltage level. The regulation method includes boost _ and buck, and stabilizes the adjusted voltage. The set voltage value. The DC-to-DC converter is mainly used in a decentralized power system, so that the front-stage power supply can be fixed to a voltage level, and the second stage can be connected to the corresponding DC-to-DC converter according to the individual power requirements of the system. . Among them, the DC/DC converter can be further divided into a pulse width modulation (PWM) power converter and a resonant power converter. Since the switching of the pulse width modulation power converter is a hard switching, resulting in severe switching loss, the power conversion efficiency cannot be improved. Therefore, the resonant power converter is exhibited, and the spectrum circuit itself has flexible switching (soft).

The first capacitor C1 is a resonant capacitor for filtering a DC component of the DC pulse outputted from the front end to participate in resonance, and combining the AC component thereof to the secondary winding of the conversion circuit 206. The rectifying and filtering circuit 208 includes two rectifying diodes, which are respectively composed of a first rectifying diode and a second rectifying diode Db, and a second capacitor C2. The first rectifying diodes Da and the second rectifying diodes Db are sequentially electrically connected to the secondary windings Was1, Wbs1 and Wbs2, Was2 of the transformers Ta, Tb, respectively. The rectifying diodes Da, Db, Dc, and Dd of the rectifying and filtering circuit 208 are used to rectify the alternating current voltage outputted by the secondary side winding into a pulsed direct current for 7 M367519. The second capacitor C2 is a filter capacitor, which mainly utilizes the charge and discharge characteristics of the filter capacitor to reduce voltage chopping to provide a relatively flat power source for the back end circuit. The main operation mode is as follows: when the square wave generates electricity, the first semiconductor element Q1 is turned on, and when the second semiconductor element q2 is turned off, a positive voltage is formed at the node p to the ground, and the converter circuit 206 is transformed into a compact voltage. When the polarity of the winding black point voltage is positive, the rectifying and filtering circuit 208 only has the first rectifying diode Da turned on and a current passes, and the current flow direction sequentially passes through the ground end and the secondary side winding Wbsl, Wasl to the The first rectifying diode Da is further provided to the back end circuit by an output terminal Vout. Since the currents flowing through the secondary windings Was1 and Wbs1 are exactly the same, the n-thin-undervoltages Ta and Tb generate the same magnetic flux and the magnetic flux balances, thereby avoiding core saturation and improving the core flux utilization. .

Referring to the fifth figure, the distribution diagram of the core operation area of the transformers Ta and Tb of the power supply device of the present invention. It can be clearly seen from the figure that the iron w operating area of the two transformers is evenly distributed in the "-" and "three-quadrant", so that the phenomenon of core saturation occurs during operation of the transformer. In addition, the device can also be used with dual output terminals (youti, v〇ut2), as shown in the sixth (a) and sixth (b) drawings, which are the third and fourth preferred embodiments of the device. The circuit diagram is mainly characterized by dual outputs.

The second rectifying diode_the fourth rectifying diode is electrically connected to a fourth capacitor C22 and a second output terminal v〇ut2. In the sixth item (6), the first rectifying diode of the rectifying chopper circuit 208 and the third rectifying diode Dc are connected to the secondary winding (10) at both ends, and the other The side is electrically connected to the -third capacitor C21 and a first output #. The second rectifying diode Db and one side of the fourth rectifying diode are electrically connected to both ends, and the other side is electrically connected to a fourth capacitor C22 and a second output ^, V〇Ut2 . The operation mode is briefly described as follows: when the first semiconductor element Q1 is turned on 'the second semiconductor element Q2 is turned off, the first rectifying diode Da is electrically connected to the third rectifying diode Dc and has a current from the two outputs. Terminal (5) also: Vout2) output to the back-end circuit. When the first semiconductor element milk is turned off and the semiconductor element Q2 is turned on, the second rectifying diode is electrically connected to the fourth rectifying diode Dd and has current from the two output ends (v〇utl, v〇ut2) ) Output to the back-end circuit. Because of its dual output and its current sharing, this device provides two identical voltages and currents for use at the back end. Referring to the seventh figure, the circuit diagram of the fifth preferred embodiment of the device, the square wave generating circuit 202 can replace the original half M367519 circuit with a full bridge circuit, the full bridge circuit includes four semiconductor components, respectively Half, the piece (1), the second semiconductor element _, the third semiconductor light guide, and the controller. The conversion! The side winding Wap and the ceramic system are connected in series to form an electric square wave. 1 = ^: When the DC power supply 2()() is input to the f-channel 202, the controller controls each of the pass and cut-off states, which can be The snacks are awkward. A q,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, . Through the magnetic dust, the lightning is generated, and the secondary winding induces an alternating current, /;, L ^ turbulent current and the alternating voltage are further passed through a whole pulse DC, and through the second 丄 two wave, A smoother power supply for the back-end circuit. Since this creation achieves the circuit design of the main f function of the current sharing function, the primary side circuit can be matched with the different forms l = . The second change - ... the primary winding - = (10) to obtain the operating voltage of each of the - secondary winding; υ : The vibration capacitor can be connected in series to the primary winding of the two parallel connections as shown in the ninth figure to achieve the function of removing the DC component and passing the AC component. Factory dog crying: According to Zongheyu, the power supply of this creation will be different in different ways: the two side windings are connected in series to make the balancer reach the flux balance, so that the current flowing through the output is exactly the same. . In addition, its circuit frame] M367519 reduces the number of diodes and the coil resistance of the secondary windings by the rectifier circuit, which can reduce component wear and improve overall efficiency. The above, only the preferred embodiment of the present invention, should not be limited to the implementation of the creation of the m, μ α ^ & equal change and modification, etc., should still be the protection of the standard.
