    • An apparatus and method for current balance in a multi-phase DC-to-DC converter with a converter output voltage and a plurality of channel currents employs for each channel a multi-input pulse width modulator or an ordinary pulse width modulator in conjunction with a multi-input comparator to produce a respective PWM signal to regulate the corresponding channel current. In addition to the comparison of the converter output voltage with a reference signal to produce an error signal, the apparatus and method compares the error signal with a ramp signal and the corresponding channel current with each of the other channel currents with the multi-input pulse width modulator. Alternatively, a ramp signal is compared by the ordinary pulse width modulator with a signal derived from the multi-input comparator which subtracts the corresponding channel current from each other channel current and sums the error signal.
    • 具有转换器输出电压和多个通道电流的多相DC-DC转换器中的电流平衡的装置和方法为每个通道使用多输入脉宽调制器或普通脉冲宽度调制器 多输入比较器产生相应的PWM信号来调节相应的通道电流。 除了将转换器输出电压与参考信号进行比较以产生误差信号之外,装置和方法还将误差信号与斜波信号和相应的通道电流与多输入脉冲中的每一个通道电流进行比较 宽度调制器 或者,通过普通脉冲宽度调制器将斜坡信号与从多输入比较器导出的信号进行比较,该信号从彼此的通道电流中减去对应的通道电流,并对误差信号求和。
