Abstract: Apparatus and method for establishing a stable operating point of a H-bridge with a center shunt switch. The stable operating point lets a circuit connected to the H-bridge outputs work in a more ideal condition. As such, an H-bridge with a stable operating point will yield a higher performance and/or save power. Since common mode is one of the biggest sources of electromagnetic interference, a stable operating point in an H-bridge also suppresses EMI.
