Error voltage ripple compensation to extend bandwidth of a feedback loop in a DC-to-DC converter |
摘要 |
Control loop ripple voltage in an error amplifier may be the result of a non-linear time varying behavior of a switch mode power conversion process. An inverse waveform replica of the error amplifier control loop ripple voltage waveform may be generated to substantially cancel the non-linear loop dynamics introduced by the control loop ripple voltage. Once the control loop ripple voltage is substantially cancelled the bandwidth of the DC-to-DC converter control loop may be increased for faster loop response thus reducing the need for additional output filter capacitance.
