Abstract:
A half-bridge direct current to direct current(DCâ€”DC) converter comprising:(a) means for receiving an input voltage (Vin); (b) means for outputting an output voltage (Vo); (c) two input capacitors; (d) an upper switch connected to one of said input capacitors and a lower switch connected to the other of said input capacitors: (e) a magnetic isolation transformer connected between said means for receiving an input voltage(Vin) input voltage and means for outputting an output voltage(Vo); and, (f) a secondary rectification circuit which bridges across said two input capacitors, wherein pulse width modulation of the upper switch is delayed at the falling edge of one signal while accelerating commencement of the rising edge of the lower switch.
