A wireless charging power supply and pick-up system during operation of electric vehicles and industrial equipment while operating is described. The withstand voltage problem on the power supply line was solved by the capacitor provided in the inverter, and the power supply line and common line arrangement. This makes it possible to extend the wireless power supply line and the economical problem of the wireless charging system is greatly improved. In the prior art, compatibility was maintained with various wireless charging pick-up pads installed in the vehicle by using a plurality of inverters. In this system, compatibility is satisfied at a lower cost by utilizing the relay present in the inverter. The EMI of the power supply line is reduced by maximizing the magnetic field cancellation effect by using the structure of the common line and the shielding tube. In addition, it improves the limitation of the length of the power supply line section and the problem of the dead zone during wireless charging while driving.

An air conditioner and a method for controlling the same are disclosed. The air conditioner implements a multistage expansion scheme by implementing serial connection between electronic expansion valves including in the R410A refrigerant-based air conditioner, and thus guarantees an optimum compression ratio in all cooling/heating load regions. Therefore, although cycle characteristics are changed by changing R410A refrigerant to R32 refrigerant, the air conditioner optimizes the cycle simply by controlling a degree of opening of electronic expansion valves, respectively. As described above, since the cycle optimization is implemented using the multistage expansion scheme in which legacy electronic expansion valves are coupled in series, the design modification is minimized without design modification of requisite constituent elements such as a heat exchanger, system implementation is facilitated, resulting in high efficiency in cost and productivity. Cooling/heating performance improvement and reliability guarantee are achieved under all load conditions, resulting in increased system efficiency.
