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 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.
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.
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 solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
