FIELD: electricity.SUBSTANCE: harmonic analyser includes a microprocessor with a digital data output, the first and the second switches, the first and the second integrating converters. The first and the second control outputs of the microprocessor are connected to control inputs of the first and the second switches respectively. The first inputs of switches are connected to an inverter, and the second inputs are connected to the input of the device; besides, the inverter input is connected to the device input, and outputs of the first and the second switches are connected to inputs of the first and the second integrating converters. Information outputs of integrating converters are connected to the first and the second information inputs of the microprocessor, the third and the fourth control outputs of which are connected to control inputs of the first and the second integrating converters respectively.EFFECT: reduction of the required computational capacity and volume of microprocessor memory.1 dwg |
