Welcome to Electrical Engineering Stack Exchange

Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about electronics design.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

Is it ok to connect 60Hz inverter to 50Hz transformer?

14

I have a car inverter (DC 12 V to AC 240 V). Inverter's frequency is 60 Hz.

I want to connect the output (240 V) of the inverter to an transformer (AC 240 V to AC 16 V) which indicates input frequency 50 Hz.

Is it ok to connect them? Will the frequency difference damage the transformer?

It is sort of OK. You will not damage it, but the efficiency probably will be lower. It could be a problem for a motor, but a transformer will probably work.

Are you sure 12V isn't enough where you are going to use 16V? Perhaps you could skip the transformer.

A 50 Hz transformer may be safely operated at 60 Hz.

An increase in losses at 60 Hz would be offset by reduction of the same due to lower flux density in the larger 50 Hz core area.


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • a specific electronics design problem
  • the theory and simulation of electromagnetic forces
  • a communication scheme
  • the writing of firmware for bare-metal or RTOS applications

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Shopping or buying recommendations
  • Consumer electronics such as media players, cell phones or smart phones, except when designing these products or modifying their electronics for other uses
  • Programming software for a PC
  • Anything else not directly related to electronics design
  • Questions that are primarily opinion-based
  • Questions with too many possible answers or that would require an extremely long answer

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

If the OP has a need for 16 volts AC, then they cannot directly use 12 volts DC. Whether 12 V AC might be good enough is a fair question but if the device wants AC, I would not feed it DC. - CCTO Oct 26, 2021 at 20:13
