What is New PWM Controller with One Cycle Response about?

This paper proposes a new nonlinear PWM control technique that has one cycle response without a resettable integrator. It forces the error between the switched variable and reference to zero each cycle by adjusting the on-pulse width, maintaining nearly constant switching frequency. Experimental results from a 100W audio amplifier show THD+N less than 0.62% and high power supply ripple rejection, demonstrating the technique
