    摘要： Cross-channel interference can be a problem in multi-channel switched power systems. A multi-channel switched power converter is provided a reference count generator that generates a reference count signal that is commonly distributed to multiple, pulse width modulating (PWM) channels of the converter. The common reference count signal counts through a sequence of successive timing values. Events in each channel are scheduled relative to the common reference count. Examples of such events include the amplification or de-application of a driving voltage pulse to an inductive means of the channel and the taking of voltage and current measurement samples. Cross channel interference is avoided or minimized by scheduling or re-scheduling events in each active channel so that they do not occur simultaneously in potentially-interfering channels, for example the taking of a current measurement sample in one channel and the turning on of an inductance-driving voltage pulse is a second channel.

    摘要： A direct current to pulse amplitude modulated (“PAM”) current converter, denominated a “PAMCC”, is connected to an individual source of direct current. The PAMCC receives direct current and provides pulse amplitude modulated current at its three output terminals, wherein the current of each terminal is one hundred twenty degrees out of phase with the other two terminals. The pulses are produced at a high frequency relative to the signal modulated on a sequence of pulses. The signal modulated onto a sequence of pulses may represent portions of a lower frequency sine wave or other lower frequency waveform, including DC. When each phased output is connected in parallel with the outputs of similar PAMCCs an array of PAMCCs is formed, wherein each voltage phased output pulse is out of phase with respect to a corresponding current output pulse of the other PAMCCs. An array of PAMCCs constructed in accordance with the present invention form a distributed three-phase multiphase inverter whose combined output is the demodulated sum of the current pulse amplitude modulated by each PAMCC on each phase.

    摘要： A power converter circuit senses the output voltage (Vo) and controls the converter's duty cycle (d1) to provide a steady output current (Io) or input power (Pin) in each switching cycle (T). During an initial period (Tramp), the controller provides a possibly smaller target current (Iramp) to reduce the system stress while the output voltage rises to a suitable value (InitVtar).

    摘要： To conserve power when regulating the output voltage (Vo) of a power converter, no adjustment is made to the converter's pulse width modulation times (Tp, Ts) even if the output voltage is off target (Vtar), provided that the output voltage does not change or is moving towards the target voltage. In some embodiments, the output voltage is not allowed to stay off target for more than a predetermined length of time. In some embodiments, the minimal adjustments are always large enough to overcome ringing (1004).
