    摘要: A selector sets respective phases of pulse driving signals in reverse when a proportion signal or integration signal does not exceed a threshold. Shifting the respective phases of the pulse driving signals from each other lowers the ripple voltage. When the load current increases drastically, the output voltage Vo tends to decrease remarkably because of the shortage of capacity in the power supply. In this case, when the proportion signal or integration signal exceeds its corresponding threshold, a phase control unit causes the pulse driving signals to synchronize their phases, i.e., the selector supplies the same ramp wave to the comparators, so that respective output voltages supplied from the DC voltage converter circuits attain the same phase, thereby restraining the output voltage supplied to the load from decreasing remarkably.

    摘要: An adder 11 outputs a signal VS indicating a value of (Vr−Vo), and a multiplier 12 outputs a control signal GS indicating a value of G(Vr−Vo) on the basis of the signal VS. An adder 13 outputs a signal HS on the basis of the control signal GS and a signal FS outputted from an operation circuit 30, and a PWM signal generating circuit 20 generates a PWM signal KS on the basis of the signal HS and a ramp signal RS outputted from a ramp signal circuit 15, and outputs this signal KS to a switching power supply. A counter 14 counts an on time of the PWM signal KS and retains a count value at a time of receiving a sample signal SMP. The operation circuit 30 has a high-pass filter 31 and an integrator 32, performs an operation based on a signal DS indicating the count value outputted from the counter 14, and outputs the signal FS after the operation.
