FREQUENCY CONVERTER AND VOLTAGE STABILISER FOR UNINTERRUPTED POWER SUPPLY |
摘要 |
FIELD: electricity.SUBSTANCE: in frequency converter and voltage stabiliser for uninterrupted power supply (UPS) an output signal is controlled in converter of one or more UPSs. Distortion stipulated at least partially by ripple voltage can be eliminated from control signal that controls entry of input current to the converter. Systems and methods described in materials of the present application provide a simple and effective method for reduction or elimination of one or more subharmonic oscillations or total harmonic distortion from input current of the converter during synchronous and asynchronous operation modes. The converter can include one or more rectifiers and inverters.EFFECT: eliminating distortion from control signal, optimising operation of the converter, reducing harmonic distortion and subharmonic oscillations from the control signal.33 cl, 9 dwg |
