Application Hint:
Temperature drift of the output carrier frequency can be cancelled by measuring both a PWM period and the on-time
of PWM (Duty) at the same time. Since both periods vary in the same direction, computing the ratio between these
values at each PWM period gives consistent measurement of the current feedback over the temperature drift.
