The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

Open-collector outputs are useful for transmitting buffered digital/pulse signals to the external world when high drive is needed. In harsh operating environments like automotive systems, however, ...

The course is focused on current-mode control techniques, which are very frequently applied in practical realizations of switched-mode. Upon completion of the course, you will be able to understand, ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

All questions and answers are based on the 2011 NEC. Q. What is the Code rule for motor control circuit overcurrent protection? A. Motor control conductors that aren’t tapped from the branch circuit ...
