High voltage boost power supply circuit : AC 220V to DC 600V switching power supply circuit
Specification:
Input voltage = 220Vac±10% 50/60Hz
Output voltage = 0~600Vdc 0.25A
Switching frequency: 70~100kHz
Design Guidelines:
In DCM mode, the output power is 200 watts
The continuous current mode calculation formula for the degradation of the input rms current is:
If the optimal operating duty cycle is set to D = 0.35, then the input peak current
Therefore, the voltage detection voltage level limit from F AN 7554 data is 1.5V
