Support for high active and low active IPM

There are two types of control signal input: high active (IGBT is ON when the input signal is High) and low active (IGBT is ON when the input signal is Low). Our photocouplers for IPM interfaces are aligned with buffer output (output signal High with LED signal ON) for high active IPM, and inverter output (output Low with LED signal ON) for low active IPM.
