I had a similar problem (starting a furnace blower from an inverter) and ended up using a centrifugal V-belt clutch. --- End quote --- You could install a ferroresonant transformer. Or a normal transformer which is undersized for the peak power would also limit the current. I do not know how well either would work. |

I did some more investigation/modeling on controls and it looks to me like micro-processor control would be fine in both continuous and discontinuous modes. But it would require knowing output voltage, inductor current and load current - to properly calculate the amount of energy to transfer without using a slow adaptive algorithm. Low frequency (eg, 5Khz) provides adequate time without too large of an inductor. |
