Average current-mode control (CMC) requires that the total waveform of the current be reconstructed for the control loop. This article presents the steps required to select the transformer and how to ...

The units feature an intuitive orange three-position (Operating, Shorting and Measuring) disconnect lever. Engaging the lever fully automatically short-circuits the transformer when using the required ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

Instrument transformers provide reliable and accurate input for the protection, control and monitoring of power grid assets such as motor control centers, UPS systems, utility metering, low and medium ...

Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator. Fig ...
