Circuit of DC To DC Converter
DC To DC Converter circuit is used to convert DC voltage to DC voltage with different concepts. DC to DC converter circuit +12 V to + /-20V is working to change the battery voltage from 12V DC to 20V DC voltage symmetrical. DC to DC converter circuit is often applied to the audio power amplifier in car audio systems.
DC to DC converter circuit uses IC TL494 as a pulse generator for the converter. TL494 IC is a PWM controller with an adjustable frequency from 40-60Hz through a potentiometer. Then from the TL494 PWM signal is given to the driver MOSFET inverter TPS2811P to be given to the power inverter with 2 units of MOSFET transistors.
