According to the development trend of switching power supply in a variety of electronic products, introduce a 12 V transfer 24 V step-up DC-DC power supply. The power supply uses TL494 as a control device, according to its working principle, a reasonable choice of power switch, filter capacitor, inductor and freewheeling diode design parameters, the use of pulse width modulation circuit control technology, and through the control switch the on-time, maintaining stable output voltage. The simulation results show that: the conversion efficiency of circuit output voltage at full load is greater than 70%, with high security and reliability.
