07 Oct 1992TL;DR: In this article, a two-way communication system is provided having a stationary device and a portable passive device, where the stationary device transmits a signal at a first frequency via magnetic field and the portable passive devices transmits coded information stored on circuitry provided therein at a second frequency also via a magnetic field.
Abstract: A two-way communication system is provided having a stationary device and a portable passive device. The portable passive device has circuitry for storing and transmitting coded information. The stationary member transmits a signal at a first frequency via magnetic field and the portable passive device transmits coded information stored on circuitry provided therein at a second frequency also via a magnetic field. An antenna circuit is provided in the portable passive device having a parallel resonant circuit and a series resonant circuit. The parallel resonant circuit derives operating power from the signal at a first frequency for use in the circuitry provided in the portable passive device. The series resonant circuit transmits coded information at a second frequency.

TL;DR: A wireless passive temperature sensor designed on the basis of a resonant circuit, fabricated on multilayer high temperature cofired ceramic (HTCC) tapes, and measured with an antenna in the wireless coupling way demonstrates good high-temperature characteristics and wide temperature range.
Abstract: A wireless passive temperature sensor is designed on the basis of a resonant circuit, fabricated on multilayer high temperature cofired ceramic (HTCC) tapes, and measured with an antenna in the wireless coupling way. Alumina ceramic used as the substrate of the sensor is fabricated by lamination and sintering techniques, and the passive resonant circuit composed of a planar spiral inductor and a parallel plate capacitor is printed and formed on the substrate by screen-printing and postfiring processes. Since the permittivity of the ceramic becomes higher as temperature rises, the resonant frequency of the sensor decreases due to the increasing capacitance of the circuit. Measurements on the input impedance versus the resonant frequency of the sensor are achieved based on the principle, and discussions are made according to the exacted relative permittivity of the ceramic and quality factor () of the sensor within the temperature range from 19°C (room temperature) to 900°C. The results show that the sensor demonstrates good high-temperature characteristics and wide temperature range. The average sensitivity of the sensor with good repeatability and reliability is up to 5.22 KHz/°C. It can be applied to detect high temperature in harsh environment.

TL;DR: In this paper, a method for controlling a resonance DC/DC converter, which adjusts an output voltage by changing a turn-on frequency of input switch devices of a resonance circuit of the converter, and extends the range of the output voltage of the resonance circuit by adjusting the duty ratio of the switch devices based on the feedback signal of the load circuit.
Abstract: The present invention refers to a method for controlling a resonance DC/DC converter, which adjusts an output voltage by changing a turn-on frequency of input switch devices of a resonance circuit of the converter, and extends the range of the output voltage of the resonance circuit by adjusting the duty ratio of the switch devices based on the feedback signal of the load circuit. The present invention also provides the resonance DC/DC converter structure using the controlling method. The advantage of the present invention lies in the use of two modes of frequency modulation and frequency modulation plus pulse width modulation to control the resonance DC/DC converter; the use of the frequency modulation controlling mode when the operating frequency of the power supply is low, and introducing the frequency modulation plus pulse width modulation controlling mode when the operating frequency of the power supply is too high. As a result, the problem of the resonance converter, that is, the high operating frequency and the big loss of the circuit when the circuit operates at a light load and non-load, can be solved, and thus the regulation ability for the output voltage of the resonance circuit is enormously improved, and the output range of the voltage is effectively expanded.

TL;DR: A new 3-D power module dedicated to SiC mosfet based on printed circuit board embedded die technology is presented and is compared with a standard power module, both modules are characterized in terms of switching behavior and electromagnetic interference emissions.
Abstract: A new 3-D power module dedicated to SiC mosfet is presented. It is based on printed circuit board embedded die technology and is compared with a standard power module. After considering the characteristics that contribute to optimal switching performances from the packaging point of view, both modules are characterized in terms of switching behavior and electromagnetic interference emissions. The results show better performances of the 3-D embedded die module with stray inductances below 2 nH and two times less common mode noise.
