Analysis over the waveforms of the electromagnetic actuators. Adaptive-delta modulation

摘要

This paper sets forth an analysis over the waveforms of the electromagnetic actuators. Due to modulation the resulted sinusoidal load current is one of the inherent drawbacks, issuing a poor response time and high losses. The following work investigates the possibility of using a particular type of modulation, which will fix the time delay problem and will decrease the losses. A potential solution to the shortcomings which occur in the case of sinusoidal modulation is the implementation of the adaptive-delta modulation, using an element with a similar behavior as the electromagnetic generator coil within the reaction loop of the modulator.
