A: Is ESD overhyped? Yet another example. If using MOSFETs only for power switching applications, it can seem like these are "robust" and "immune" to ESD events. While the package clearly states "ESD sensitive", devices never seem to fail from ESD - why? Because power MOSFETs have a very large gate and other capacit... (more) |

A: How is it possible to perform a open circuit test on a induction motor? To truly "open circuit test" a motor as I interpret it, remove it from power, and measure the following: Using an Ohmmeter, measure each winding resistance. Start from W1 to W2. This will be some value, such as 5.1Ω. Measure U1 to U2 and it should be very close to the previous value; within 1... (more) |

Note, automotive applications can see a "load-dump" pulse of about 80V for a very short time. It is a really harsh electrical environment. I once built a blinking LED using a 2N3906 to switch on when the ignition was off (poor man's fake car alarm.) Worked great for a year or two, then one day, it... (more) |

A: Why arc welding does not require high voltage to arc? In addition, welding in general doesn't require high voltage, but rather high current. As Olin explains, the high voltage is only needed to get the shielding gas ionized into a plasma state - then the high current is what keeps it going and hot. So most welders intentionally reduce the incoming e... (more) |

MPPT is definitely used in production. It's not really efficient for a single cell, except for testing.

A: How to check realistic specs of small solar panel? For a "better way", research Maximum Power Point Tracking (MPPT.) The solar cell will produce some number of Volts and Amps. But the amount of power (VA, Watts) a solar cell produces is not simply "when one is at maximum." For instance, the most current will happen when the load resistance is ... (more) |
