To make a stream lined ic tl494 pwm modified sine wave inverter, the iron core transformer could be swapped with a ferrite core transformer. the winding particulars for the same could possibly be noticed below: by means of super enamelled copper wire: primary: wind 5 x 5 turns center tap, choosing 4 mm (2 2 mm strands wrapped in parallel). Inverter ic tl494. before constructing the circuit using the tl494 pwm controller, let's understand how the tl494 works. the tl494 ic comprises 8 functional blocks, outlined below: 5 v reference regulator: the ref pin (pin 14) provides a stable supply for internal circuitry, including the pulse steering flip flop, oscillator, dead time control.
