I have an H-Bridge required to allow reversal of polarity in an electromagnet at 4 Hz. In particular, the specifications state 600 V, 80 A using IGBTs; in a situation in which only 50 A is delivered by a 12 V DC source. I have two questions: first whether such an H-Bridge is appropriate; and second, whether a simple 555 IC timer can be wired to it to cause the desired rate of switching.
I have a general idea of how a 555-timer works to deliver an output pulse to the IGBTs; but am unsure whether on its own it is capable of triggering the necessary effect in such a case.
