Multi-channel pulse width modulated signal interleave and inversion

A multi-channel signal processing system reduces electromagnetic interference (EMI) by staggering pulse edges of one or more pulse-width modulated signals (PWM signals) to prevent pulse edge overlap with at least one of the other PWM signals and inverting at least one of the PWM signals. Staggering and inverting the PWM signals reduces the total EMI power at any given time generated by the multi-channel signal processing system. Pulse edges can be staggered by advancing or delaying a pulse edge for one or more channels. Pulses can be staggered and inverted using static interleave and inversion subsystems or dynamically using controllable interleave and inversion control systems. In at least one embodiment, the multi-channel signal processing system includes high power, half-bridge amplifiers for each channel. The timing and phases of the PWM signals can be determined to reduce EMI from the half-bridge amplifiers caused by the PWM signals.
