Abstract: The ionizer feedback control converts high-voltage signals to feedback signals to monitor the corresponding high-voltage signals and compares the feedback signals to a first specification to determine whether the feedback signals are within the first specification. The ionizer varies a frequency and a duty cycle of a digital signal to control an excitation signal for a step-up transformer and modulates the frequency and the duty cycle of a step-up transformer output voltage to consistently maintain the feedback signals within the first specification and maintain the high-voltage signals within a second specification to generate consistent ion concentrations over a range of electrical signal inputs. The microprocessor calculates and reports high-voltage signals, and ion concentrations based on feedback signals.

Abstract: The present disclosure discloses a resistive sub-module hybrid MMC and a direct current fault processing strategy thereof. The hybrid MMC prevents fault current from entering a direct current system from the alternating current side by artificially creating three-phase earthing short circuit on the alternating current side of a converter during the direct current fault processing process, and can reduce the number of required power electronic devices compared with the module hybrid MMC. At the same time, the direct current fault processing speed of the hybrid MMC is fast, and the duration of the artificially creating three-phase short circuit fault in the fault processing process is less than 60 ms, which will not have a great impact on the alternating current system. The present disclosure greatly reduces the cost of building an overhead line high-voltage flexible direct current transmission system, and has very strong reference significance and use value in engineering.
