Abstract
Disclosed herein is a DC-AC converter, in accordance with some embodiments. Accordingly, the DC-AC converter comprises a transformer, a pulse generator, a pulse modulator, a switching element, and an analog low pass filtering stage. Further, the pulse generator is configured for generating pulses characterized by a pulse frequency. Further, the pulse modulator is configured for generating a pulse density modulated signal based on modulating the pulses using a sine wave signal of a fundamental frequency. Further, the switching element is connected in series with a primary winding of the transformer. Further, the switching element is configured to be switched between an on state and an off state based on the pulse density modulated signal. Further, the analog low pass filtering stage is configured for generating an AC voltage of the fundamental frequency based on attenuating higher frequency components of an unfiltered AC voltage at a secondary winding of the transformer.
