Patent ID: 8742293

Claim:
An inverter rectifier output circuit, said circuit comprising: a secondary winding of a transformer, said secondary winding having a first node, a second node, and a center tap node; a first saturable reactor connected to said first node; a first rectifying diode connected in series with said first saturable reactor at an anode of said first rectifying diode; a second saturable reactor connected to said second node; a second rectifying diode connected in series with said second saturable reactor at an anode of said second rectifying diode; a third saturable reactor connected to said center tap node; a free-wheeling diode connected in series with said third saturable reactor at an anode of said free-wheeling diode; a first series RC network connected between said anode of said first rectifying diode and said anode of said free-wheeling diode; a second series RC network connected between said anode of said second rectifying diode and said anode of said free-wheeling diode; a first output node defined by connected cathodes of said first rectifying diode, said second rectifying diode, and said free-wheeling diode; a second output node defined by said center tap node; wherein the third saturable reactor has an inductance less than the first saturable reactor and the second saturable reactor at least during switching.
