There are 2 protection circuits. One is a current
sensor, there's a
current transformer in series with the chopper transformer primary
winding. The other is a set of voltage sensors.
Whatever you do, don't disable any of the trips. If there really is
something wrong, the results would be spectacular!.
Do you get any voltage appearing on any of the outputs? Even for that
half-second?
Today I have dedicated another time to this power supply :)
The SG3524 is correctly powered, it receive about 8V to its power pin and
give 5V on the reference output.
The sawtooth signal is present and good, like the oscillator output.
The inhibit pin is not active.
When I switch on the power supply, voltages on the outputs make a little
pulse, but of less then one second.
I'm workingo on :)
