Multipurpose half-bridge DC-AC converter

The power converter consists of a half-bridge MOSFET device with an appropriate driver, an output filter and a modulator. The load is connected between the center of the half-bridge and the center of the symmetrical supply. The dimensioning of the output filter and the modulator is especially treated. The circuit is applicable for generating AC power supplies, for driving a phase of a step- or induction motor, as a high dynamic DC motor drive, as a high dynamic actuator control, as a class-D amplifier for AF (audio frequency) applications and as a general purpose power amplifier. The frequency, step and burst response for an example are shown
