TL494: TL494 for invertor application

Sammi Shang

Part Number: TL494
Other Parts Discussed in Thread: TIDA-01426,

Dear team,

I wonder if TL494 could used for 100W, DCAC application. Customer need 12V vin, 110AC(sine wave) output. I see we have a reference design TIDA-01426 could applied for 1W application.

Please help confirm if TL494 could be used or any other device could be recommended.

Thanks.

Best regards,

Sammi

    Hello Sammi

    I don't think the TL494 will work. It lacks the ability to produce a bipolar output easily. You can see that the TIDA-01426 design uses the TL494 to generate a high voltage DC and a linear amplifier to produce the sinusoid - it would not be practical to use this arrangement at 100W.

    I was able to find only a few DC/AC inverter designs in our reference designs library - please give me a few days to ask some colleagues for their opinions.

    Regards

    Colin

    Hi Colin,

    Thanks for your response. Please kindly help check if TL494 or other device could support >30W application. Customer choose TL494 because they saw an article that describe TL494 are used in automobile charger or cigarette lighter that could support 30W. But as the article is chinese and not wrotten by Tiers, so I hope product line could help give some suggestion.

    Thanks.

    Best regards,

    Sammi

    Hi Sammi

    The TL494 can be used in the way that the customer schematic shows - one TL494 device producing a high voltage and the other TL494 producing an alternating square wave at 50Hz through a pair of totem pole MOSFET switches. We'll continue the conversation via email and I'll close this thread.

    Regards
