ALTERNATING CURRENT INJECTION FOR CONSTANT-ON TIME BUCK CONVERTER - A REGULATOR CONTROL METHOD

摘要

The present invention discloses a voltage control method. At first, the load voltage of the load is divided to generate a feedback voltage. The feedback voltage and a triangular wave of a triangular wave periodic signal, including the positive voltage and negative voltage, are combined to generate a sum signal. The sum signal is compared with a target voltage, and when the sum signal is less than the target voltage signal, a control signal is generated to control the switches to turn on or off. Finally, the switch receives the control signal and accordingly providing an input voltage to update and stabilize the load voltage.

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.
