Abstract:
A converter comprising:an input power connection; a controller; a feedback circuit; a drive; a low side drive driving a low side switch; a high side drive driving a high side switch; an isolator device; a transformer; an output rectifier circuit; said output rectifier circuit providing a signal to the feedback circuit; said feedback circuit providing a signal to the controller; said controller providing a signal to the low side switch and to the isolator device; said isolator device providing a signal to the high side switch; a positive input terminal of the input power connection connected to a first node of a first N-Channel device; said positive input terminal further connected to a capacitor and to a resistor and further connected to a first node of the isolator device; a second node of said isolator device connected to a second node of the first N-Channel device; said transformer providing isolated outputs from auxiliary windings to said output rectifier circuit; said transformer further comprising a magnetic element operating in a non-saturated region (NSME); a capacitor connected to a first terminal of said NSME; a third node of the first N-Channel device connected to a first node of a second N-Channel device and a second terminal of said NSME; and a negative input terminal of the source connected to a second node of the second N-Channel device and to a return node of the high side switch.
