VOLTAGE CONTROL METHOD |
| 摘要 |
The present invention discloses a voltage control method. First, the load voltage of the load is divided to generate a feedback voltage. Then, an absolute value of a periodic triangular wave signal is retrieved to generate a positive feedback signal, which and the feedback voltage are then combined to produce a sum signal. The sum signal is then compared with a target voltage and when the sum signal is less than the target voltage, a control signal is generated and thus the load voltage is updated and stabilized using an input voltage. In an alternative method, the feedback voltage and the periodic triangular wave signal are combined to generate a sum signal, which is compared with the target voltage. When sum signal is less than the target voltage, a control signal is generated and thus the load voltage is for updated and stabilized using an input voltage. |

1. A voltage control method comprising the steps of:
dividing a load voltage of a load to generate a feedback voltage and capturing an absolute value of a periodic triangular wave signal to produce a positive feedback signal; adding the feedback voltage and the positive feedback signal to produce a sum signal; comparing the sum signal with a target voltage, wherein when the sum signal is less than the target voltage, generating a control signal; and receiving the control signal and accordingly updating and stabilizing the load voltage using an input voltage. |
