![]() This would mean less efficient and more bulky DC-DC converter. Now, achieving higher ROFs requires further voltage increase, plus higher voltage applied to the mag means the converter has to supply more current. But then I had to increase its output voltage from 9 to 14 volts (so in-out difference was reduced). ![]() DC-DC converters are efficient when there is significant difference between input and output voltages. Originally, it was implemented because we needed to lower mag voltage from 24 to 9 volts with minimum losses. Here's the ideology behind the design changes: let's say good bye to DC-DC converter, we don't need it any more. It's $10 cheaper (no need for DC-DC converter). Better transistor in mag control circuit.ĥ. Mag voltage is controlled with a jumper (see below).ģ. What it inherits from the previous design:Ģ. Please welcome the board ver.3 (Sergey's board - 2). ![]()
