<p>An integrate assembly (300) includes a power converter module (2) having an input bus bar, an output bus bar, an n-level converter (10) and driver circuitry (13) adapted to control the n-level con0.verter (10), in response to received control signals. The n-level converter (10) 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 (300) includes DC-DC switching power supply (12), having an input (18) for receiving a DC input voltage, for generating a DC output voltage and providing it to a load (20). The switching power supply (12) includes controlled switching devices (22), each having an input terminal (24) and an output terminal (26). Each of the controlled switching devices (22) 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.</p> |
