Embodiment Construction
[0051] Please refer to Figure 7 , which is a flow chart of the control method of the DC-to-DC converter of the present invention. First, continuously monitor the DC output voltage (step S10). When the DC output voltage is less than the first threshold voltage (step S12), then jump to step S10; otherwise, when the DC output voltage is greater than the first threshold voltage (step S12), then increase the frequency of the PWM signal, that is, Increase from a first frequency to a second frequency (step S14). Next, continuously monitor the DC output voltage (step S16). When the DC output voltage is greater than the first threshold voltage (step S18), then jump to step S16; otherwise, when the DC output voltage is less than the first threshold voltage (step S18), then restore the frequency of the original PWM signal, that is , decrease from the second frequency to the first frequency (step S20), and skip to (step S10).
