Power factor correction circuit for DC-DC converters with low resonance currentAn improvement in a power factor correction circuit with ZVS provides low resonance current. The basic circuit includes a positive input and ground terminal and an output capacitor connected between a positive output terminal...
The X-ray machine power factor correction circuit further comprises an auxiliary switching circuit, which is mainly composed of an auxiliary switching power tube VT1, a fast recovery diode VD1, a fast recovery diode VD2 and a resonant inductor Lr. The X-ray machine power factor correction ...
In a scannable D master-slave flip-flop circuit with synchronous preset or clear capability, the output of the slave latch is gated with the scan-enable signal to form the scan-data-output signal. This output gating of the scan-output data that allows for considerable simplification of the in...
Cr√fr1=1Lr+Lm.Cr . From Figure 14, the LLC resonant converter gain M is evaluated using voltage divider law by considering the load quality factor Q and transformer step-up ratio as shown in Eq. (21). M=VoVin=ZiZo=F2(AL−1)n(fs2fr22−1)2+(Q(F3−F)2(AL−1))2√M=...
circuit of a first transistor Tr1 and a second diode Dc2 is connected in parallel with the series circuit of a first diode Dc1 and a second transistor Tr2 between the first rectified output terminal t1 of an AC single phase power supply S and the joint of a choke coil Lr and a diode ...
The data logging box can simultaneously receive the joystick voltage outputs through a modified electrical circuit of the PWC control board. These signals are converted to the angular displacements of the joystick in the FB and LR directions, which are used to evaluate the accuracy of the proposed...
When implemented in a LatticeSCM-15E FPGA packaged in a space-saving 256 fine pitch Ball Grid Array (fpBGA) package, the bridge solution requires a mere 17mm x 17mm on a printed circuit board while consuming only 2.5Watts of power, substantially less than competitive devices. In s...
However, it is still a major factor in energy consumption. A server cooling system must ensure that each and every component meets its specification. Most components have damage, functional, and reliability temperature specifications as seen in Figure 4-17. A well-designed thermal management scheme...
The photon-induced electrical transport properties are further analyzed utilizing a Parallel circuit model. Due to the realization of optimized carrier concentrations by photon activation, the power factor of Cu2S film is improved more than 900 times as compared with the dark data. As compared to ...
Thus there is a trade-off between the operation bandwidth and the power limit performance in the choice of Q factor. In addition, we noted that two photon absorption (TPA) and free carrier absorption (FCA) may act as important roles in silicon micro- cavity, as Johnson et al. mentioned ...
