Abstract:
A DCâ€”DC converter comprising:an input having a first terminal and a second terminal; an output having a first terminal and a second terminal; a transformer having a first winding and a second winding, each winding having a first end and a second end; the first end of each winding being connected to the first terminal of said input; first and second rectifying diodes, each diode having a first terminal and a second terminal; the first terminal of said first diode being connected to the second end of the first winding; the first terminal of said second diode being connected to the second end of the second winding; the second terminal of each said diode being connected to the first terminal of said output; first and second switches that turn on and off in response to control signals, each switch being connected between the second end of one of the first and second windings of said transformer and the second terminal of said output; and a controller for generating first and second control signals for controlling said first and second switches to turn on and off alternately at a selected repetition frequency.
