<p>The invention relates to radioelectronic engineering, in particular to AC signal converters, and can be used as an autonomous AC voltage electrical power supply source and for other purposes. The proposed AC signal converter remains functional when one or more or all but one of the DC voltage sources fails and makes it possible to increase, to an unlimited degree, the output power thereof on account of an increase in the quantity of AC signal amplification and conversion stages and DC voltage sources. Furthermore, a square-wave AC input signal is converted into a signal of, or close to, any set shape (sinusoidal, saw-tooth etc.) at the amplification and conversion stages, at an output matching element, at the output of the amplification and conversion stages, at the output of the output matching element (transformer) or output matching elements (transformers), and, for loading the proposed AC signal converter, an AC signal which is optimal for this load is supplied. The proposed AC signal converter is characterized by a high degree of efficiency, low heat and power losses and also low costs.</p> |
