a phase is different over a wide range in a high-frequency power-supply apparatus in which high-frequency power which is always in a resonance state by controlling an inverter is supplied to a load comprising an LCR series resonance circuit in a high-frequency circuit such as a tank circuit...
resulting in a very low spike current during latch up and improved paralleling turn on. The capacitance between the gate and the first electrode may be increased, which may reduce the Q factor of LCR series circuit during paralleling turn off. Hence the turn-off oscillation problem may be impr...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Characteristic impedance, Zchar, of the resonance can be determined by: Zcℎar = LPAR CPAR (7) 5. Rsnubber in the RC snubber circuit should equal Zchar above, and the capacitor, Csnubber, should be sized to be multiple times the parasitic capacitance, CPAR. A factor of about 7x was...
After adding an inductor or a capacitor to the four LC resonance circuits to regulate the input impedance, it can form the well-known T-circuit or Π-circuit. 3 Analysis of novel parameter tuning method for LCC/LCC compensated IPT system 3.1 New tuning method New compensation topologies can ...
and a resonance capacitor203. The power receiving apparatus200further includes a transducer204that brings the AC power to a power factor of one by setting parameters of the transducer on the basis of circuit constants measured in advance. The transducer204converts the AC power to DC power and ...
Q factor FOD (FOD/qf) 2. Resonance frequency FOD (FOD/rf) The receiver sends FOD/rf and/or FOD/qf packets during the negotiation phase. The Tx responds to these packets with an ACK packet if no FO is found and with a...
This paper focuses on the study of a soft-switched unidirectional boost-type rectifier employing a snubber circuit, used as a front-end converter stage in high-power applications. The proposed rectif...
After the re-poling process of the UT, the quality factor increased from 1231.1 to 2418 to minimize the unwanted heat generation. To support this UT, we also developed a custom-made generator with a transformer and developed 2nd harmonic termination circuit, control microcontroller with an ...
