5. C switching MOSFET is 700 mA Take care that under no circumstances the peak current in the primary winding of the T1 transformer exceeds 700 mA Resistors R1 R2 R3 and R4 limit the inrush current The resistor must be a carbon resistor because metal film resistors can act as a fuse in this position If no inrush current limiting is required the resistor can be replaced with a short circuit e EMl filtering is implemented using separate stages for common mode L1 and differential mode L2 Depending on the requirements the filtering stage can be adapted For example inductor L1 can be chosen to ensure that its leakage inductance takes care of differential filtering As a consequence L2 can be omitted Surge voltage protection is implemented using TVS diodes D9 D10 D11 D12 and capacitors C5 C6 The surge protection limits the DC bus voltage to 800 V The TVS diodes choice determines the maximum allowable surge pulse energy Resistors R17 R18 and R19 form small pre loads for the converter When the output voltages are adjusted also adjust the pre load resistors to ensure that they consume roughly the same amount of power Depending on the connected load eliminate the resistors Zener diodes D21 D22 and D23 are an elementary output OverVoltage Protection OVP When OVP is not needed eliminate the diodes Capacitors C11 C13 and C15 are used to obtain additional HF voltage stability and noise suppression Eliminate the
