The dynamics of the voltage feedforward input is limited downwards at 0.5V (see
that is the output of the multiplier will not increase any more if the voltage on the V
below 0.5V. This helps to prevent excessive power flow when the line voltage is lower than
the minimum specified value (brownout conditions).
