Abstract
The current invention relates to a power conversion device (), for supplying a load () with a PWM signal through an inductive output filter (). The power conversion device () comprises a power conversion module () supplied by a DC input voltage (Vin) and is configured for providing a plurality of output signals (PWM, . . . , PWMn) having a level amplitude that is a fraction of the input voltage (Vin) level. Each output signal is floating with a bias component equally split in a plurality of steps ranging from a determined lowest fraction level amplitude to a determined highest fraction level amplitude. The power conversion device () further comprises a multiplexer () receiving as a plurality of inputs the plurality of output signals (PWM, . . . , PWMn). The multiplexer is configured for outputting one output signal (PWMx) selected from the plurality of inputs, whereby the output signal (PWMx) of the multiplexer () is connected to the output filter ().
