“…And, these parts were made up by various static and dynamic components, such as phase-shifting transformer, series rectifier, inverter and induction motor. The different parts concerned different electric quantities (industrial AC, DC and variable AC) (Evans and Limpaecher, 2009). All of the factors mentioned earlier lead to the complicated fault type and characteristics of variable frequency drive system.…”

The complicated structure and high power density make the protection and control of high voltage power frequency control system difficult. This paper proposed the novel protection and control strategy covered different parts of the system. Taking advantage of microprocessor protection system realised the system-level protection covered the fault of rectifier input, DC link, inverter output and even the induction motor. Improve the main circuit to strengthen security and stability in device level. The paper also analysed the cooperation of the protective trip and PWM pulse blocking and validated the feasibility of dual breaker setting to restrain feedback energy.

“…However, it is really the necessity, what can reduce drastically the cost, production time, and the reproducibility of a filter or layout design before randomly taking any EMI issues solution process. On the other hand, although the issue of output CM voltage has been pointed [16], to our best knowledge, no cost-effective method has been presented to deal with it.…”

In this paper, a family of secondary-side commonmode (CM) noise suppressers is proposed for off-line switchingmode power supplies (SMPSs) used in fault current limiter (FCL). Not only the operation principle of the proposed secondary-side CM noise suppressers is quite straightforward, but also the circuit configuration is extremely simply. Hence, component size as well as cost of the off-line can reduced significantly. An off-line Flyback-type power converter using the proposed CM noise suppresser is analyzed in detail, finally, along with some experimental results to verify the performance and effectiveness of this power supplies.

“…However, it is really the necessity, of implementing ways to reduce the cost drastically, shorten production time, and enhance the reproducibility of a filter or layout designthat must be considered addressing any EMI issues in the solution process. On the other hand, although the issue of low-frequency CM output voltage has been pointed put [16], if appears as though no cost-effective method has been presented to deal with this issue.…”

This paper presents a design for an electromagnetic interference (EMI) power filter which is serially-cascaded with a conventional off-line switching-mode power converter to reduce the non-intrinsic differential-mode (DM) EMI and low-frequency common-mode (CM) output voltage in switching-mode power converters (SMPCs). The circuit configuration is extremely simple so that the size of the component can be reduced as well as its cost. Additionally, the operating principle of the proposed EMI power filter is also quite straightforward. An off-line flyback-type power converter, using the proposed EMI power filter, is analyzed in detail. Finally, some experimental results are provided in order to verify the performance and effectiveness of this converter.
