DC-DC and DC-AC Series or Parallel Hybrid Converters

This paper presents a discussion and contributions about linear and switched converters associated, including some particularities. Audio amplifiers, calibration systems, inverters applied in motor drivers, where is necessary to mitigate the current over the bearings, magnetic resonance, where harmonics generate distortions in the images and other applications that need high-quality signals are the best options to use these approaches. In these applications, the power supplies must cancel the ripple that is found in switched converters and maintain the high efficiency. Some structures are presented, simulated and built. The results are presented in order to prove the expected characteristics.
