A power factor correction circuit comprises first and second ac inputs (I1), (I2) for receiving an ac voltage. A rectifier (104) has first and second rectifier inputs (I3), (I4) each connected to a respective ac input (I1), (I2), and first and second rectifier outputs (05), (...
The frequency of the power source affects the maximum power output in an LC circuit as it determines the rate at which the inductor and capacitor exchange energy. At the resonant frequency, the maximum power output is achieved because the inductor and capacitor are in phase and the exchange of...

An object of the present invention is to provide an LC circuit unit capable of further improving the power transmission efficiency while reducing the influence of a leakage magnetic field from a planar coil. A planar coil 2 including a winding portion 2a wound in a planar spiral shape, a magn...
In this case, an AC or DC short circuit may occur and damage the inverter. The resulting device damage is not covered under any warranty. Since the output of the PV string connected to the inverter cannot be grounded, ensure that the PV module output is well insulated to ground. Terminal...
This paper proposes a boost integrated two-switch forward AC-DC light-emitting diode (LED) driver with a high power factor and ripple-free output inductor current. In the proposed LED driver, the maximum switch voltages are clamped to the voltage level of the DC-link capacitor without an RCD...
Figure 12 reflected the relationship between the load quality factor, AC = AL = 1 and LCLC voltage gain depending on the switching frequency as shown in Eq. (20). MV=1[1+AC+AL−AC(fsfr)2−AL(frfs)2]2+[1Q(frfs−fsfr)]2√MV=11+AC+AL−ACfsfr2−ALfrfs22+1Qfrfs−fsf...
The transformer as employed in a voltage-mode power combining configuration in order to attain high output power across a wide frequency bandwidth. The output power of the CMOS PA at the fundamental signal was further enhanced by using a LC circuit that suppresses the harmonics. The reconfigurable...
