Gelbanana tested 3 HV SMPS Nixie power supplies for their efficiency. The tested ICs were the always popular NE555 timer, the MC34063 buck/boost controller, and the MAX1771 boost controller. The MAX1771 was the most efficient, but it also costs 10x more than the other two ICs tested. Table with the results of the test can be found below the fold.
Today I’ve decided to test the efficiency of the different design of HV SMPS that I’ve built a while back. I used a 240v neon bulb which I salvaged from a panel mount light indicator. The bulb draws about 1.5mA and I’ve used 2 pieces. MAX1771 have the best efficiency but comes with a pricey price tag.
