2) 41V Output voltage
2-1) 41V Output
FET Q151 is in ON status during normal operation, conducts to main converter output and the potentiostatically-controlled volt-
age is output.
Q151 is in ON status when the sub winding voltage of coil L201 of 15V output converter has force applied to it.
2-2) 41V Output Overcurrent Protection Circuit
This circuit consists mainly of R161, Q152.
When Overcurrent flows to R161, the voltage potential difference of R161 is detected, Q152 is turned ON, and Q151 is turned
OFF.
Consequently the fold back current limiting shuts down 41V output.
