We investigated multiphase buck converter in ripple control DC - DC power supply with constant on - time (COT) control by simulation. In the ripple control power supply, since there is no fixed clock inside due to the fluctuating cycle, the period is detected by the peak hold voltage based on a saw-tooth wave circuit. As a four-phase system, by quartering the peak voltage and comparing them with the saw-tooth wave, a set of four-phase PWMs is generated to obtain stable current balance
and excellent response characteristics. Compared to single phase converter, low output ripple and fast transient response are shown. As a result, the output voltage ripple was greatly reduced and the supply of large output current was confirmed. Moreover, we confirmed the element sensitivity of the current balance, it turned out that the sensitivity of the on time error of the main control PWM signal was high and the influence of the other element variation was small. |
