What is a tl494 IC?
The circuit shown in the schematic is a PWM signals based inverter circuit using a TL494 IC. This IC is commonly used for voltage regulation and switching applications like SMPS. The TL494 operates as a pulse width modulation (PWM) controller which generating switching signals to drive transistors Q4 and Q5.
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.
What is a tl494 oscillator?
The TL494 is a fixed−frequency pulse width modulation control circuit, incorporating the primary building blocks required for the control of a switching power supply. (See Figure 1.) An internal−linear sawtooth oscillator is frequency− programmable by two external components, RT and CT. The approximate oscillator frequency is determined by:
How does tl494 work?
The circuit takes a 12V power input from connector J6. The connector J2 is used to take out the PWM signals generated by the IC. The resistors, capacitors, and diodes around the TL494 set the operating frequency and duty cycle.
