SETUP:
In one of our R&D application we are using two core per product.
One as primary-coil and other as secondary coil. Primary core has 40turns and secondary has 400 turns center-tapped as 200Turns.
Primary core is excited at 2V-Vpp at freq range of 6KHz-10KHz. These core arrangements has a loop of resistors going through each core. The voltage developed at secondary winding is inversly proportional to the value to resistors in the loop. We are monitoring the voltage developed at the secondary windindgs
QUERIES:
1. Are there any chances of core degradation if this setup is made to run for longer duration (years). If yes, What could be the possible reasons for core degradation in longer runs ?
2. What are the necessary precautions/preventive measures need to be taken to avoid the core degradation ?
3. How should we calculate maximum flux density & maximum power that can be handled by this specific core ?
4. It was observed that the voltage at the secondary coil was not constant in the event of constant input sine signal and fixed resistors. Please provide insight on this
5. Is this core temperature & humidity sensitive. If yes, what is working temperature range ?
