SMPS_1: Isolation transformer

• just for Isolation - designed ideally to 60kV - in real life it will be much less
• potted in epoxy 22kV/mm = 3mm gaps between PRI/SEC and core = very high leakage inductance = soft source
• half bridge topology was chosen due to high leakage inductance.
• idealy no feedback at all = problem due to leakage inductance - soft source
• to minimize leakage inductance, primary winding will be splitted in hlaf. PRIM | SEC | PRIM
• 20-50kHz

SMPS_2: classic buck converter

SMPS_3: step up

SMPS_4: current or voltage fed voltage converter - depends on power (e-beam weldes vs SEM)

• Mains -> DC, buck, full bridge
• FPGA driver
