WebJun 26, 2015 · during the time the HT is not applied, the power supply has no load and then presents its maximum voltage; because it will create a current inrush specially in the power tubes that can -- for a short moment -- drive the tubes far above their max dissipation. The idea is to apply the HT gradually. Using a vacuum rectifier is a way to achieve this. WebBenchtop setup of a clean phantom power supply using demonstration circuit DC2628. The tests were run with 16 V input, but the performance will be similar with 12 V to 24 V IN . Some applications may require boosting from 5 V, which can be accomplished by decreasing the LT8362’s switching frequency from 2 MHz to 1 MHz to allow for the 75 ns … WebFor the filament supply I used a simple 7812 regulator circuit to reduce noise.
