An integrated assembly includes a power converter module having an input bus bar, an output bus bar, an n-level converter and driver circuitry adapted to control the n-level converter, in response to received control signals. The n-level converter switches between a pair of voltage levels selected from a set of n levels, where n>=3. The integrated assembly also includes a controller providing the control signals to the driver circuitry, and fiber optic lines connecting the driver circuitry of the n-level converter to the controller. The integrated assembly includes DC-DC switching power supply, having an input for receiving a DC input voltage, for generating a DC output voltage and providing it to a load. The switching power supply includes controlled switching devices, each having an input terminal and an output terminal. Each of the controlled switching devices receives a portion of the DC input voltage and each has a voltage-rating characteristic that is less than the DC input voltage. The sum of these voltage-rating characteristics for each of the controlled switching devices is greater than the DC input voltage.
