Patent ID: 10224716

Abstract:
Embodiments herein provide an ACsDC converter for generating an ACsDC signal in which AC or DC source can be used to generate the ACsDC signal. The structure of the ACsDC converter consists of three stages, viz., input, isolation, and output. At the input stage, a DC voltage is converted to two AC voltages using power electronic converters. The isolation stage consists of transformers for isolating load and source terminals. The secondary voltages of the isolation transformers are used for obtaining the AC and DC components of the ACsDC signal. At the output stage, the AC component of the output voltage is obtained by using an AC-DC converter and a DC-AC converter. The magnitude, phase, and frequency of the AC component can be controlled. The magnitude of the DC component is controlled using a modulation technique. The AC and the DC component can be combined to obtain the ACsDC signal.
