The high voltage power supply for magnetron, used for the modular micr
owave generators in industrial applications, is of a classical design:
a single phase leakage flux transformer supplying a cell, composed of
a capacitor and a diode, which multiplies the voltage and stabilizes
the current. A pi model of this transformer is developed, taking the s
aturation phenomena and the stabilization process of the magnetron cur
rent into account. Three inductances are characterized by the non line
ar relations between flux and magnetizing current. This model was test
ed by E.M.T.P. software (Electro-Magnetic Transients Program), near th
e nominal state. The theoretical results were compared to experimental
measurements with a good agreement.
