Abstract:
1. A rectifier, comprising: a reference primary circuit; a transformer having a primary side connected to said reference primary circuit and having a secondary side; first and second rectifiers in synchronous connection at said secondary side, said first and second rectifiers each having at least three leads, one of said three leads being a control lead; first and second clamping transistors, said first clamping transistor being connected between said control lead of said first rectifier and said secondary side, said second clamping transistor being connected between said control lead of said second rectifier and said secondary side; a first damping resistor connected to a control lead of said first clamping transistor and a second damping resistor connected to a control lead of said second clamping transistor; a load connected to a same winding of said secondary side as said first and second clamping transistors; and a fixed voltage source connected to said first and second damping resistors to supply a fixed voltage to said control leads of said first and second transistors.
