A tapped winding flyback converter comprising: a transformer, wherein the transformer has a primary winding and a secondary winding; a first switch coupled to the primary winding so as to control the flow of current through the primary winding; a second switch coupled to a tapped portion of the secondary winding; and circuitry coupled to the first switch and the second switch, configured to: switch the first switch using a first duty cycle and turn the second switch off, so as to allow current to flow through a first number of turns of the secondary winding of the transformer, wherein the first number of turns is less than the total number of turns of the secondary winding of the transformer, thereby outputting a low voltage; switch the first switch using a second duty cycle wherein the first duty cycle is equal to the second duty cycle and turn the second switch on, so as to allow current to flow through a second number of turns of the secondary winding of the transformer, wherein the second number of turns is larger than the first number of turns of the secondary winding of the transformer, thereby outputting an intermediate voltage; and switch the first switch using a third duty cycle that is greater than the second duty cycle and turn the second switch on, so as to allow current to flow through the second number of turns of the secondary winding of the transformer, thereby outputting a third high output voltage level. a transformer, wherein the transformer has a primary winding and a secondary winding; a first switch coupled to the primary winding so as to control the flow of current through the primary winding; a second switch coupled to a tapped portion of the secondary winding; and circuitry coupled to the first switch and the second switch, configured to: switch the first switch using a first duty cycle and turn the second switch off, so as to allow current to flow through a first number of turns of the secondary winding of the transformer, wherein the first number of turns is less than the total number of turns of the secondary winding of the transformer, thereby outputting a low voltage; switch the first switch using a second duty cycle wherein the first duty cycle is equal to the second duty cycle and turn the second switch on, so as to allow current to flow through a second number of turns of the secondary winding of the transformer, wherein the second number of turns is larger than the first number of turns of the secondary winding of the transformer, thereby outputting an intermediate voltage; and switch the first switch using a third duty cycle that is greater than the second duty cycle and turn the second switch on, so as to allow current to flow through the second number of turns of the secondary winding of the transformer, thereby outputting a third high output voltage level. switch the first switch using a first duty cycle and turn the second switch off, so as to allow current to flow through a first number of turns of the secondary winding of the transformer, wherein the first number of turns is less than the total number of turns of the secondary winding of the transformer, thereby outputting a low voltage; switch the first switch using a second duty cycle wherein the first duty cycle is equal to the second duty cycle and turn the second switch on, so as to allow current to flow through a second number of turns of the secondary winding of the transformer, wherein the second number of turns is larger than the first number of turns of the secondary winding of the transformer, thereby outputting an intermediate voltage; and switch the first switch using a third duty cycle that is greater than the second duty cycle and turn the second switch on, so as to allow current to flow through the second number of turns of the secondary winding of the transformer, thereby outputting a third high output voltage level.
