Abstract: Under weak grid, permanent magnetic synchronous generator (PMSG) is prone to occur subsynchronous resonance (SSR), which seriously threatens the security of power systems. First, the ...

Abstract: This paper introduces a novel single-loop control scheme for voltage regulation in islanded inverters, using a proportional-integral-lead (PI-Lead) controller designed within the synchronous ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

Spending more time in glucose range could help reduce adverse pregnancy outcomes, but available closed-loop insulin delivery systems are not customized to pregnancy-specific needs. In a randomized ...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...

This is Part 2 of a three-part series. As discussed in Part 1 and recapped here, modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher ...

Negative feedback can create a control system where the output of a process is used to counteract any deviations from a desired set point, effectively “correcting” the system, bringing it back to ...

The learning organization has been a unifying concept in the field of organizational development, first introduced by Peter Senge in 1990. Its relevance has not diminished but instead is becoming more ...

Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current ...
