“Power diode thyristors are widely used in AC/DC converters, UPS, AC static switches, SVC and electrolytic hydrogen, etc. However, most engineers do not understand such bipolar devices as well as IGBTs. For this reason, we organized 6 Article serial, including forward characteristics, dynamic characteristics, control characteristics, protection, loss and thermal characteristics. “ Power diode thyristors are widely used in AC/DC […]
On December 25, the first event of the “Smart Dual Gigabit, Enabling Digitization” to promote the interactive experience exhibition of Shanghai’s urban digital transformation results was held in the South Plaza. The interactive experience exhibition is guided by the Municipal Commission of Economy and Information Technology, the Municipal Administration of Communications, and the Minhang District Government, sponsored by Shanghai Mobile […]
“The circuit drives a high-power white light LED (WLED), when the temperature is too high and the thermistor has an open circuit or short circuit fault, the LED will be turned off. If working outside the extreme operating temperature range, the life of any IC will be shortened. When the junction temperature of the chip exceeds a certain value, it […]
“The evaluation of analog switches, multiplexers, operational amplifiers and other ICs poses a challenge for IC test engineers. A typical test requires applying a test voltage or forced voltage to the input of the device and measuring any resulting leakage current and offset current, which is often performed at the level of 1pA or lower. The low-power measurement circuit in […]
“Surface acoustic wave technology is an emerging science and technology developed in the late 1960s. It is a marginal subject combining acoustics and electronics. Since the propagation speed of SAW is 100,000 times slower than that of electromagnetic waves, and it is easy to sample and process on its propagation path, using SAW to simulate various functions of electronics can […]
[Guide]This article will demonstrate how to select the correct power supply tolerance for your design. Specifically, this article will use the LTpowerCAD resistor divider toolbox to show how to use component tolerances and estimate the corresponding error in the output voltage. With this information, designers can correctly determine the allowable tolerances for their applications. Introduction Power can be found in […]
