Hi Walter,
I am sorry for carelessly screwing up on my lossless resistance
postings. The arithmetic wasn`t the center of my attention. I should
have been more careful. I`ve apologized to Steve Nisko.

Starving the load for power during a percentage of the cycle limits
power as surely as limiting current all of the time.

Time limitation can be nearly lossless. Resistor limitation is lossy and
reduces efficiency.

Best regards, Richard Harrison, KB5WZI
