PWM Modified Sine Wave Inverter Circuit Employing IC TL494 In this article we talk about an adaptable IC TL494 PWM Modified Sine Wave Inverter which contains the IC TL494 for the vital sophisticated PWM reproduction.
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.
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.
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.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
