Developments in power electronic switches and low-cost actuator based on an electronic controller have made it possible to design and implement many functions for a new electric brush cutter. Such an attempt has made in this work by using an electronic controller to control this new brush cutter. Certain important issues in design including the making(More)
This paper aims at researching the effects of voltage-sag events upon AC electromagnetic contactor (abbreviated as AC contactor) and developing a compensation strategy based on feedback control approach. An AC contactor model is first analyzed when sags event is ensured occurrence as well as a novel voltage compensation strategy is designed for timely(More)
Developments in power electronic switches and lowcost actuator based on an electronic control module (ECM) have made it possible to design and implement modern control strategies for a new AC permanent magnet (PM) contactor. Such an attempt has made in this work for a colenoid actuator controlling the AC PM contactor. Certain important issues in design(More)
