The comparator 206 is electrically connected to the first specific point a of the auxiliary 2 group 225 and the step-down transformer 224 to measure the voltage phase of the specific point a. For example, in a preferred embodiment of the invention, the comparator 2G6W measures the voltage phase VLr of the drain inductor with the leakage inductance u. The phase-price measuring devices 2〇8 are electrically connected to the comparator 鸠 and the half-bridge converter respectively to measure the voltage phase of the first-specific point a and the second specific point b. For example, in the preferred embodiment of the present invention, the phase detecting means 2 〇 8 can measure the voltage phase value of the first specific point a and the second specific point ^ 9 1315121 A l ftTM! voltage phase VdS2, - Age t WT·UV? / 弟一特疋 point b is located at the extreme of the second switch. The voltage feedback device 210 is electrically connected to the load 204 for (4) the voltage of the load 2 () 4 . The voltage adjustment circuit 212 is electrically connected to the voltage feedback device 210 for receiving the feedback signal of the load 204, but the feedback signal of the voltage is adjusted. The phase-locked control circuit 214 is electrically connected to the voltage. The adjustment circuit 212 and the phase-sampling device 208' the phase-locked control circuit 214 have a phase comparator 226, a back-to-sequence-low-pass ferrite 228, and a galvanic control shunt 23 〇. The phase comparator 226 and The phase illusion is connected to the relay, and is used to input the phase (4). The voltage phase of the first specific point a and the second specific point b detected by the device is phase locked, and is rotated to the voltage control. The comparator 230' and the phase comparator 26, '' output a reference voltage from the low-pass filter 228, compare with the voltage adjustment circuit 212 and the adjusted feedback signal, and output the comparison result to the voltage control oscillation The voltage control oscillator 23 outputs a square wave frequency signal to the half bridge driving circuit 222, and adjusts the switching frequency of the first switch 218 and the second switch 22% to provide a stable voltage of the load 204. ° Month > Test 3 _ 'the department Another circuit diagram of a CLL resonant power converter having a phase locked loop control function of the present invention is shown in Fig. 2. The difference between the auxiliary winding and the comparator 206 is shifted, and the first specific point a is shifted. The positive terminal of the first rectifying diode to the whole device 216 is electrically connected to the step-down transformer 224 = one-human side. This connection method can save the auxiliary winding and the comparator to save cost. The function of the phase-locked control circuit used in the phase-locked control circuit of the present invention is to track the function of frequency. First, observe the voltage and current in the half-bridge converter 10 1315121 9 Included. Man i 曰 replace page i phase 'assumed to select half bridge The converter Μ - the specific point & and the third phase and locked in the twist, that is, the load coffee from the start to the steady state of the temple, / fish two points of the phase maintain the Za / (four) relationship. When the circuit is steady When the & = two phases are at θ degrees, via the phase lock control circuit 214, the switching frequency (fSW) of the i, the material should be switched to the first switch 218 and the second switch 22: The operating frequency is fsw', which corresponds to the large voltage gain The voltage gain required for the steady state of the load 204. Then, the above parameters are used to design the component parameters in the spectral circuit in the half-bridge converter. Then, the /^ and (4) difference amount at the specific vibration frequency The smaller the difference, the better. When: The difference between a/b and Θ is zero, the function of phase-locking to track the Wei frequency is reached. The phase-locked control circuit of the present invention can achieve the operating frequency chasing (four) vibration frequency. The effect 'When the operating frequency is at the resonance point or the inductance is closer to the resonance point, not only can avoid excessive virtual power consumption', but also the voltage gain generated by the resonant circuit can be more effectively utilized. However, in the actual circuit During the design process, the variation of the input voltage and the output load will cause the voltage gain characteristic variation of the CLL resonant tank. In order to avoid the shortage of the output voltage, the output/input voltage gain is usually designed to be larger than the originally required voltage gain. Still high. When there is excessive voltage gain, the voltage feedback device 210 and the voltage adjustment circuit 212 control architecture can be used to limit the gain of the voltage. In a preferred embodiment of the invention, the voltage feedback device 21A and the voltage adjustment circuit 212 retrieve the voltage of the load 204 and compare it with the desired load voltage in the voltage regulation circuit 212. When the feedback voltage is greater than the desired voltage value, the voltage adjustment circuit 212 sends a high potential to the voltage-connected voltage control oscillator 230 to drive the voltage control oscillator 23 to increase the rate of 1315121. The square wave frequency sent by the voltage control oscillator 230 is increased or decreased; 掸: the switching frequency of the switch 218 and the second switch 220 can achieve the effect of reducing the benefit. In this manner, the phase lock control circuit 214 receives and integrates the half-bridge switch=two specific points of the electric house signal through the detecting device 208 and the voltage adjusting circuit 212'. Second, to output a frequency signal to the half-bridge driving circuit 222, to perform the phase effect, the negative voltage 胄2G4 has over-voltage protection' and maintain the stable voltage. The preferred embodiment of the present invention can be seen as an advantage of the present invention. That is, the device is for the i-vibration: phase:: control function of the CLL spectrum type DC power conversion low-spectrum circuit component; the error of the number of sizes has a higher tolerance, can be reduced by the preferred embodiment of the invention In the second invention, the spectral frequency variation, but the lock tracking frequency of the present invention has a high tolerance to the load variation error.
