Tl494 makes home inverter

How does a tl494 inverter work?

The inverter works based on the switching IC of TL494. The IC generates high-frequency pulses (about 30khz). The pulses are amplified by the MOSFET of IRF3205 and pass through the transformer. The Fast diodes are rectified and give the power output.

How does IC tl494 work?

A very simple yet accurate and stable inverter circuit using IC TL494 is shown in the below diagram. The inverter includes a feedback control system for automatic output voltage correction, applied at the error amplifier pin#1 of the IC. The 100k preset can be adjusted appropriately for setting up the required constant output voltage limit.

Why should you choose a PWM IC tl494?

The use of the PWM IC TL494 not only makes the design extremely economical with its parts count but also highly efficient and accurate. The IC TL494 is a specialized PWM IC and is designed ideally to suit all types of circuits which require precise PWM based outputs.

How many functional blocks does the tl494 IC have?

The TL494 IC has 8 functional blocks, which are shown and described below. The 5V internal reference regulator output is the REF pin, which is pin-14 of the IC. The reference regulator is there to provide a stable supply for internal circuitry like the pulse-steering flip-flop, oscillator, dead-time control comparator, and PWM comparator.
