Classification: CPC H  Y | IPC H

Claim 7:
8. A method of providing power for a multi-channel amplifier, the method comprising:
receiving, with a multi-phase power factor correction (PFC) circuit, input mains alternating current (AC) power;
boosting, with each boost stage of a plurality of boost stages of the multi-phase PFC circuit, the input mains AC power to a final PFC output voltage, the multi-phase PFC circuit including a first array of fault detection and protection devices, wherein a first set of fault detection and protection devices is coupled to each of the respective boost stages for each phase of the multi-phase PFC circuit;
receiving, with a system controller and via a first interface between the multi-phase PFC circuit and the system controller, first fault information from the first array of fault detection and protection devices;
transmitting, with the system controller, the first fault information to components that are configured to provide failure compensation measures based on the first fault information; and
summing, with a first output combinatorial circuit of the multi-phase PFC circuit, a first output voltage from each of the respective boost stages to produce the final PFC output voltage.
