    摘要: Device and method for measuring electrical current, for measuring current will drastically reduce labor costs that occur during physical installation of current transformer and software configuration of current transformer type and transformation rate (on measuring device side). Protection/auto detection/communication circuit in connection with RJ12 port on both current transformer and measuring device side will zero out any potential damage to current transformer or injury to user, due to wiring error. Auto detection/communication circuit will be implemented into each current transformer. Auto detection/communication circuit will be directly connected to RJ12 port which will assure plug and play compatibility with available measuring devices. Combination of auto detection/communication circuit, RJ12 port and compatible measuring device will drastically reduce labor costs. Current transformer needs only to be connected to measuring device, using single cable with RJ12 connector, everything else is done by auto detection/communication circuit, which will provide measuring device with current transformer transformation ratio and transformer type. No other configuration is needed on measuring device side when connecting current transformer. Auto detection/communication circuit also enables factory calibration of current transformers. Factory calibration on both current transformer and measuring device drastically improves system accuracy (accuracy of both current transformer and measuring device).

    摘要: A fuel cell power controller tracks load current and fuel cell output voltage, and alerts on excessive fuel cell ramp rate, so another power source can supplement the fuel cell and/or the load can be reduced. A power engineering process makes efficient use of available fuel cell power by ramping up power flow rapidly when power is available, while respecting the ramp rate and other power limitations of the fuel cell and safety limitations of the load. Power flow decreases after an alert indicating an electrical output limitation of the fuel cell. Permitted power flow increases in response to a power demand increase (actual or requested) from the load in the absence of the alert. Power flow may increase or decrease in a fixed amount, a proportional amount, or per a sequence. A power controller relay may trip open on a low fuel cell output voltage or high load current.

    摘要: A replica circuit (115) for a buck converter senses a replica of the current through the low-side switch transistor MLS without using a sense resistor. The replica circuit includes a replica transistor (MREP1, MREP2) and a current sense amplifier CSA, which drives the replica transistor with a first replica current, which is a scaled version of the current through the low-side switch transistor MLS, and generates a second replica current. A resistor (305) converts the second replica current into an output voltage (CSAOUT). A sample switch error amplifier integrator circuit (351) including a sample switch (S1) and an error amplifier (EA) samples the second replica current during a sampling window to generate an error signal (VERR). A controller controls the high-side and low-side switch transistors (MLS, MHS) responsive to the error signal.

    摘要: Embodiments include apparatuses, systems, and methods including a switching converter having an output stage including a power switch or first switching device to convert an input switching signal to an output switching signal and a sensor stage including a second switching device and a third switching device. In embodiments, the sensor stage may be coupled to receive the output switching signal from the first switching device and to substantially replicate a condition of the first switching device to generate a continuous signal rather than a switched signal. In embodiments, the continuous signal may allow detection of a current level. In some embodiments, the current level may indicate an overcurrent event. A digital post-processing circuit may be coupled to the switching device to count a number of overcurrent events according to various embodiments. Other embodiments may also be described and claimed.
