Abstract:
1. A regulator control method comprising the following steps: dividing a load voltage of a load to generate a feedback voltage; receiving the feedback voltage and a periodic triangular wave signal, the triangular wave signal having a positive voltage and negative voltage, and adding the feedback voltage and the triangular wave signal to generate a sum signal; comparing the sum signal to a target voltage, generating a control signal when the sum signal is less than the target voltage; receiving the control signal, and accordingly providing an input voltage to update and stabilize the load voltage; wherein receiving the triangular wave signal comprising the following steps: receiving a periodic trapezoidal wave signals, each cycle of the trapezoidal wave signal comprising an initial voltage, a sampling signal and an end voltage chronologically, an absolute value of the initial voltage is greater than an absolute value of the end voltage; and capturing an average of the initial voltage and the end voltage of a first cycle, subtracting the sample signal of a second cycle following the first cycle from the average of the initial voltage and the end voltage of the first cycle to produce the triangular wave signal.
