"That statement is dependent on the RC time constant "I thought it had more to do with the value of the first cap and the fact that the diodes can't turn on (conduction angle) until the voltage at the transformer is larger than the voltage across the cap (forward biasing the diode). And I thought the charging current peak is high because the diode will only be on for a short time but still needs to deliver the same power as it would if (they) were on for the entire half cycle (like they are when a critical inductance choke follows the rectifiers instead of the first cap).
I think Lynn is looking at the first half of this spike and calling that "fast" (.001 second from nothing to .59 amps) as the thing that needs to be "slowed down".
