New Twist on Phase-Shedding

An “eco mode” method for managing parallel arrays of power modules in an intermediate-bus power-distribution system optimizes efficiency across loads better than conventional approaches commonly used to boost power supply efficiency, such as pulse skipping or the use of low-power “standby supplies.” The technique is similar to phase shedding, which is often used to optimize light-load performance for multi-phase buck regulators, which are used to provide low-voltage, high-current power to microprocessors. In this case, however, the implementation is different as the “phases” are actually independent power components and the technique is employed at the...
