Description
Summary:This paper deals with a new application of DC/DC regulators for the achievement of a sine wave output. More particularly, synchronised current control modulator MC 2 in a buck configuration is discribed to generate an AC waveform at 50 Hz. Large signal simulation is detailed which concludes on the setting of a sawtooth corrective network to avoid the structural instability for V 0 >> V/2. It is shown that small signal analysis can be applied for such application and mathematical models for discontinuous and continuous conduction modes are presented. The paper ends with the test of a breadboard generating a pure sine wave without harmonic content at 85 % efficiency.
