Hi,
Thanks for your valuable feedback.
Here, 10ohm resistor is the internal resistance of the coil.
Would you be kind to explain me the following point?
1. What the functionality of 10m ohm resistor in the circuit?
2. What are the purposes of using C1 and C2 along with the resistors in parallel.
Thanks & Regards.
C1 and C2 are an easy way to allow the half-bridge (at left) to act as a full H-bridge. The capacitors establish a node, midway between VCC and 0V ground.
The 10m resistor would be unnecessary except that the simulator calls it an error to place capacitors in series.
My simulation is chiefly good for demonstrating how a concept might work. There were many arrangements which I tried but which did not work. Such as which component to measure the differential voltage, what sequence the LCR components should be, which input and output specs work for the op amp. Etc.
I found that the op amp responds properly when it senses voltage transitions across the resistor. This can be a small ohm value, inline with your inductor.
Your schematic has a full H-bridge. This is preferable over my schematic, if you wish to drive greater current through the LCR. However your control circuit will need to be more complex.
My circuit can go into stagnation. This will allow severe shoot-through. You may need to set some amount of dead time (as implied in post #9). You may need to use two or more separate control devices. Etc.
You may also need to provide protection from high-voltage spikes caused by the inductor when inadvertently switched off suddenly. Etc.
