Hello Community

Please help me with the formula for calculating the Number of Turns in the Primary and Secondary windings of the Low-Frequency DC to AC Inverter Transformer project.

I want to design a 3KVA low-Frequency transformer. The input DC voltage is 24VDC, the Output AC voltage is 230 and the AC voltage power is 3KVA.

Please let me hear from you

Thanks

    Hi, Thank you for posting on the Volt.Tech community. Can you please share a detailed block diagram of the Inverter system? Is it the same as the below-attached block? This operation note from Infineon depicts a sample figure for a low-frequency converter. Regards, Julian

Hello, What should be the voltage across VBAT and VBAT- of the M4Z32- BR00SH1 battery at the moment of purchase? However, can it be recharged? If it’s zero at the time of purchase. Thank You

    Welcome, to the community! The voltage between both terminals should be nominally 2.8 V, below 2.0 V it should be considered discharged. The battery is based on lithium carbon monofluoride chemistry and isn't rechargeable. Does it answer your question? Regards Alex

What I see is that the eval board output the power thru the terminal block, I’m curious how it’ll auto-select the voltage demanded. that’s no additional signal or feedback connected to the eval board.

The first device can auto-select to output five 5V also follow Bluetooth speaker devices, it auto-generates 15V. Let’s say I want to connect to an Uno board. which is DC 7- 15V, how will the eval output be?

I am using 20V source power)

    EVAL- SCS001V1 is grounded on the STUSB4500, which can store three PDO profiles( power data objects) in its NVM and informs the connected power force( source) of the voltage and current to be supplied.

    Since the EVAL- SCS001V1 has no information about the needed voltages and currents of the connected loads( sinks,e.g. your UNO), these values have to be stored in the NVM of the included STUSB4500. Programming can be done. g. with the GUI STSW- STUSB002.
    As soon as the EVAL- SCS001V1 with your UNO board is connected to the USB- C power force, the set power can be requested.

I would like to know the level of Renesas RA2E1 ADC internal reference voltage. Is it fixed or adjustable? What voltage is it?

We are making 10 watt flood light with sic IC  and we are facing issue with 4kv and 440volt because if we use mov 561 then surge pass 4kv and high voltage pass only 400volt and if we use mov 621 then surge fail at 3.5kv and high voltage pass 440volt , please suggest the mov which one can use those we can achieve 4kv and 440volt pass both parameter .

    Hi ,   There is only issue with MOV tolerance if you use less tolerance mov or High Surge MOV your issue will be solve Thanks sandeep
