Expert bulk transporter ALE explains ‘complexities’ of moving 143-tonne electrical transformer through Surrey | Power Inductor Coil

GaN- and SiC-based power devices are making inroads in BEVs, but they are not widely used in some power blocks. For example, the traction inverter incorporates a network of power semiconductors. OEMs mainly use IGBTs, which are cost-effective solutions here.

Have a look. I used Engauge Digitizer to read the graphs in the data sheets:https://hackaday.io/project/12696/log/43883

“I got the driver section and the bridge [output] all figured out and assembled, as well as the tank capacitance circuit, but then I sat on it for a couple of years. Finally, a friend nudged me to complete it, and I did so in about six  months.”

10+ Amps at 30V Drain to Source. Vgs around 2.5 threshold so it’ll work from a 3V uC. On paper should be able to switch it around 10MHz but definitely it can take 20kHz to get above hearing range.

I got a bag of MTA3055 Enhanced N-channel FETs from one of the surplus places and have successfully switched 12v 4-5A inductive loads using 5v Arduino-atmega logic with no intermediate drivers. I believe the “enhanced” part is important, but I can’t tell you what has been “enhanced”.

At Baptist Church Road and Regional Road 22, where 500kW and 230kW transmission lines meet, two significant developments underway will add more power to an already high-voltage crossroads.

This story has been updated. Ontario Power Generation leases its Kincardine nuclear property to operator Bruce Power.

The release said “smoke and steam were seen coming from the door leading to a transformer vault on the second floor,” and Commonwealth Edison was called to the scene — with a request to expedite their arrival.

Abstract: An indicator assembly for determining a liquid level condition within a tank includes a dial assembly with a base and a lens or cover connected to the base. A channel is formed in the lens and a go-no-go protrusion projects into the channel. An actuator is located between the base and the cover and is movable in response to a change in liquid level in the tank. The indicator assembly also includes a sensor module for insertion into the channel. The sensor module has a housing with a sensor for determining movement of the actuator in response to a change in liquid level. A go-no-go cavity complementary in shape with the go-no-go protrusion is formed in the housing so that the sensor module can be fully inserted into the housing with the sensor aligned with the actuator for generating signals related to the liquid level condition.

In talking to Professor Lee, he noted that the classic Tek 465 oscilloscope did not have a T-coil to drive the CRT (cathode ray tube), to its detriment. Lee told me. “Tek put a T-coil in the next-to-last stage, but no T-coil driver on the CRT plates. I go through the calculations, and they’re giving up 30% of the bandwidth by not putting one on the output stage.”

The Newton High-Voltage Transformer was the incineration site. Here, in a fenced-in yard off along a 403 ramp in Westdale small birds regularly get zapped like mosquitoes but larger birds, such as the one found smouldering in the yard on April 17, can cause a disruption large enough to trip breakers.
