4 FAQs about Tl4941 inverter voltage output low

What are tl494 resistors?

Resistors R2 and R8 set the control voltage for the feedback loop, the set voltage is connected to pin 2 of the TL494 IC, and the feedback voltage is connected to pin one of the IC labeled as VOLTAGE_FEEDBACK. The resistors R10 and R15 set the current limit in the circuit.

How do I know if my tl494 is saturating?

Measure the feedback voltage going back to the TL494 to verify the opto curreent is reponding to the changes in +OUT. Did you intend for the second opto LED to be on? If not, make sure the second opto LED is OFF. Force it to always be OFF because I believe it is always fully ON and this is saturating the TL494 feedback voltage.

Can TL431 sink current?

The TL431 can only sink current but you would be replacing the TL431 with your op amp which can source current. Also, you mentioned you were trying to load +OUT=340V with 200mA. This is 68W - what is your intended output power when the converter is working properly?

What is inverter low voltage?

Now that we know what inverter low voltage is, let's explore some common causes behind it. One prevalent cause could be a faulty battery. An old or damaged battery may not be able to provide sufficient power, leading to low voltage from the inverter. Another possible cause could be an inadequate power source or improper electrical connections.
