    Abstract: A motor drive or bus supply power conversion system includes a rectifier with at least one rectifier switch module for rectifying AC input power. A DC bus is connected to the rectifier and supplies DC output power. An optional inverter is connected to the DC bus and includes at least one inverter switch module for inverting the DC bus voltage to an AC output power. The at least one rectifier switch module and the at least one inverter switch module each include a base plate and a housing connected to the base plate. The housing defines an interior space that contains at least one semiconductor switch. A protective cover layer includes a corrosion protection material and divides the interior space into an inner sub-space located between the base plate and the protective cover layer and an outer sub-space located between the protective cover layer and the housing. The at least one semiconductor switch is located in the inner sub-space such that an atmosphere in the outer sub-space passes through the protective cover layer of corrosion protection material before entering the inner sub-space. Additional anti-corrosion features are provided including a conformal coating on printed circuit board assemblies, removable connector covers, dielectric grease coated connections, nano-coated fiber optic transceivers, and an exterior protective film wrap.
