8. Amplitude on the EXTAL pin after startup is determined by the ALC block, that is the Automatic Level Control Circuit. The function of the ALC is to provide high drive current during oscillator startup, but reduce current after oscillation in order to reduce power, distortion, and RFI, ...
For example, such a device displaying a 10 dB return loss may show more than the calculated 0.7 dB increase in gain when finally matched to −20 dB return loss. 2. Circuit losses can play havoc with the k-factor, and especially the frequency where it crosses unity. In practice, ...
Equivalent circuit theory is applied to research the MCRWPT system based on the two-coil model with SS structure in this paper [26]. The equivalent circuit model is shown in Figure 1, where the 𝑈𝑆US represents the alternating current power supply. The internal resistance 𝑅𝑆RS of ...
Investigating the performance of power electronics devices and thus power inverters at cryogenic temperatures for electric aircraft systems are of great interest. Accordingly, the purpose of this study is to examine the inverter circuit technologies used in cryogenically-cooled electric aircraft applications...
An Agilent E4980A precision LCR meter was used to determine the capacitance and dissipation factor under an applied bias field. A Radiant Technologies Precision Premier II tester measured the hysteresis loops. The capacitor samples were immersed in Fluka silicone oil (Sigma-Aldrich) during ...
Power Factor - Basic Introduction - Reactive and Apparent Power. What is difference between real power and apparent power? The power dissipated by a loadis referred to as true power. ... Total power in an AC circuit, both dissipated and absorbed/returned is referred to as apparent power. Ap...
8. Amplitude on the EXTAL pin after startup is determined by the ALC block, that is the Automatic Level Control Circuit. The function of the ALC is to provide high drive current during oscillator startup, but reduce current after oscillation in order to reduce power, distortion, and RFI, ...
9. Conversion offset error must be divided by the applied gain factor (1, 2, 4, 8, or 16) to obtain the actual input referred offset error. 10. This parameter is guaranteed by bench validation with a small sample of devices across process variations, and tested in production to a value...
Dead time between the complementary driving signals is needed to avoid short circuit in voltage source inverters (VSIs), however, this raises issues such as voltage distortion and harmonic generation. In wireless power transfer (WPT) systems, the ratio of dead time versus operating period becomes ...
