Sine-cosine modulator


The invention relates to a self-oscillating pulse-width modulation amplifier in the form of a sine-cosine modulator (10) comprising at least two comparators (13, 14), two integrators (11, 12), a power switching stage (15), and negative feedback coupling with a low-frequency signal input and output. To achieve a maximum modulation factor, there are provisions with the aid of the comparators (13, 14) and integrators (11, 12) for the generation of sine- and cosine-square-wave voltages and sine- and co-sine-triangle-wave voltages that drive the power switching stage (15) in part, wherein the output of the power switching stage (15) combined with an lc low-pass filter (16) forms the low-frequency signal output.

Discontinuous pulse width modulation


A discontinuous pulse width modulation technique is used in a controller to control an inverter that converts dc battery power to ac power to operate an electric motor, e.g., in a hybrid electric vehicle. The discontinuous pulse width modulation technique uses only one of the two zero state voltage vectors in its calculations whereas traditional pulse width modulation uses both zero state voltage vectors.
