![]() ![]() Example: a 4-bit counter will have a maximum of 16 states. The number of states sets the size of the counter. Use a counter to clock through all these states. ![]() Work out from the graph, how many states there are in a complete sequence. Possible to easily change if you make a mistake in your design.Īnother way to generate these signals is to use "discrete logic" - CMOS logic ICs. I would personally use a simple micro-controller to create these signals but you say you don't know how to program these (you could learn). These often have circuits inside that prevent top and bottom switching on simultaneously. Each H-bridge can (should) be a special IC designed for the purpose. From the graph, you can work out the sequence of these signals. ![]() So you will need 10 logic signals from your driving system (2 for each H-bridge). Obviously, at no time will the top and bottom transistors be on together.Low - top transistor off, bottom transistor on.High - top transistor on, bottom transistor off.You also have the waveform graph.Įach H-bridge needs two inputs, one for the top transistor and one for the bottom. You have the circuit showing 5 H-bridges.
