H bridge Circuit
Here you can see that I just interchanged the position of transistors. Remember that transistor is a current controlled device. The switching speed of a transistor is around 10Khz . So if you want more switching speed you have to go for MOSFET which is having speed around 100K. Second thing MOS is a voltage controlled device. Suppose if a device you are using have high voltage and current rating (suppose if you are driving a big motor), then you can use relay circuit to make H-bridge. Try to make the circuit and see what are the practical limitations.
