    • A multi-phase power converter and a method for balancing a plurality of currents in the multi-phase power converter. The multi-phase power converter that includes a pulse width modulator coupled to an oscillator. A plurality of currents are generated in response to output signals from the pulse width modulator. The levels of the currents are sensed and a sense signal is transmitted to the pulse width modulator. Switching circuitry within the pulse width modulator switches signals from the oscillator in accordance with the current levels, the levels of the signals from the oscillator, and whether at least one of the signals from the oscillator is either rising or falling.
    • 一种多相功率转换器和用于平衡多相功率转换器中的多个电流的方法。 多相功率转换器,其包括耦合到振荡器的脉宽调制器。 响应于来自脉冲宽度调制器的输出信号产生多个电流。 感测电流的电平,并将感测信号传输到脉宽调制器。 脉冲宽度调制器内的开关电路根据电流电平,来自振荡器的信号电平以及来自振荡器的至少一个信号是上升还是下降来切换来自振荡器的信号。
