Inverter 150 Watt using TL494   Keywords - TL494 IC: Pulse-Width-Modulation Control Circuit   Introduction to TL494 It supports all of the functions that are necessary for the Pulse Width Modulation (PWM) control circuits. Power supply control is the basic purpose of TL494 device. Its has an output control circuit, a flipflop, dead time comparator, two different error amplifiers, 5V reference voltage, oscillator and a PWM comparator. TL 494 operates properly between the frequency of 1kHz to 300kHz.The Dead Time Comparator (DTC) provides around 5% of dead time. Both of he error amplifiers displays a common mode voltage from -0.3V to (Vcc-2)V. If we provide sawtooth wave at CT terminal and terminate RT to the reference output (Vref), oscillator will be bypassed. Internal circuit of TL 494 resists the double pulse at the output. TL494 has a wide range of applications e.g. microwave ovens, PC’s, washing machines, Solar power inverte...
