Drone Wireless Charging System (드론무선충전)
 
03:45
For more information of drone wireless charging system, please visit our website : http://tera.kaist.ac.kr Wireless power transfer (WPT) technology enables convenient and automatic battery charging for unmanned aerial vehicles (UAVs). Therefore, we demonstrate 200 Watts class Drone Wireless Charging system using WPT technologies. This WPT charging step is divided into 3 stages. 1st stage refers to the drone landing on WPT charging platform. 2nd stage refers to the Drone Wireless charging. The last stage refers to the drone taking off from WPT charging platform. First step is the drone landing on WPT charging platform. Once the drone has landed on the platform, the power is transferred to battery in drone wirelessly. Wireless charging parameter, battery voltage, input current, charging power can be monitored in real-time using 2.4 G Wi-Fi communication. And the regulator provides the function of CC-CV mode, which is an effective way to charge lithium batteries. The Coil to coil efficiency is 91% and the overall efficiency is 72%. DGPS is utilized instead of GPS for more accurate landing. DGPS information, such as the drone location and its attitude also can be monitored. 200 Watts-class resonant WPT charging system for drone consists of a 60kHz inverter, Tx and Rx windings, resonant topologies, a regulator and a battery. High-frequency operation and WPT system with high coupling coefficient are used to reduce the size and the mass of drone WPT system. And, we proposed and fabricated the WPT landing plate considering the coil alignment. The Tx part and the Rx parts contain the windings with ferrite to complete the magnetic path .The core structure can reduce the leakage electromagnetic field. The charging method using magnetic field has electrical safety advantages. And we, proposed Three Phase Resonant Magnetic Field charging scheme for Low EMI and EMF. Elimination of the 3rd harmonic components is possible via three-phase inverter. The three-phase system has very small power ripples compared to those of the single-phase system. Current flowing through the three phase resonant magnetic field system to transfer 200 watts to the battery is smaller than that of the singel phase resonant magnetic system. And we also proposed High Q Multiple Resonant Reactive Loop Shielding (MRRLS) for EMI and EMF Reduction. In the near future, our development of the drone wireless charging system on the automotive vehicle can provide a tangible solution for delivery systems, surveillance systems and unlimited possible applications

The integrated regulator of voltage IR3870M ...
 
02:57
The integrated regulator of voltage IR3870M SupIRBuck SupIRBuck is the innovational line of the POL( point-of-load) DC-DC single-channel voltage regulators with a broad inlet range, integrating the management microcircuit QFN 5х6 mm and the HEXFET field transistor within a low-profile frame. Due to the unique microcircuit layout, the SupIRBuck voltage regulators offer a simple, flexible, low-cost, compact and efficient POL converter solution. The company International Rectifier released into the market the new integrated voltage regulator of the series SupIRBuck IR3870M for notebooks and table computers, gaming consoles, user electronics (LC TV-sets, printer etc.), digital TV-games attachments, POL DC-DC converters of general use. IR3870M is a totally integrated DC-DC voltage regulator, convenient in usage and developed especially for the effective transformation of voltage at loads from small to complete. The IR3870M microcircuit is a hysteresis regulator with a fixed switching time, control of the 'dead time" zone and measurement of the outlet current on the keys. All the above integrated opportunities of the microcircuit promote the efficiency increase of the notebook supply bocks. The IR3870M regulator supplies the load of up to 10 amperes at the working temperature of 60°С and has the diode emulation for the effective functioning of the system on small loads. To increase the coefficient of efficiency in the range of average and total load the microcircuit is equipped with a pump for pumping the lock charge. Besides, the IR3870M is remarkable with its broad range of inlet voltages (3 - 26 volts) and the programmed level of outlet voltage between 0.5 and 12 volts, realized by the means of the exterior mounting of the resistors. Other peculiarities of the regulators include the shift launch, the precise source of the supporting tension of the 0.5 volts voltage, protection from increased and decreased inlet voltage, the enable inlet with the voltage control. The microcircuit allows constant control of the switch time, programming of the transformation frequency and the soft launching along with current protection.

A New Dual Bridge Series Resonant DC DC Converter with Dual Tank
 
00:21
Compared to the dual active bridge (DAB) converter, the dual-bridge series resonant converter (DBSRC) can widen soft-switching range. To further widen the soft-switching range and improve the circuit performance, a new dual-bridge series resonant converter with dual-tank based on DBSRC is proposed in this paper. This new converter features two resonant tanks and a tapped-transformer, and it can perform better than the DBSRC by optimized tap-coefficient x of the tapped-transformer. Its operation principle, voltage gain, the soft-switching characteristics and output power are analyzed in detail, and compared with the DBSRC. Results show that the proposed dual-tank topology has presented higher voltage gain, wider soft-switching region, and larger output power than the traditional DBSRC when the tap-coefficient x is selected reasonably. At last, a 1kW prototype is built; experimental results verify the feasibility and advantages of the proposed dual-tank converter.

In this video, he delves further into time-domain measurements of power supply signals using oscilloscopes, sometimes in combination with specialized adapters such as current injectors. He presents examples of various waveform anomalies and discusses techniques and tips for observing them as well as pitfalls to avoid. Sandler also advises designers on minimum and recommended specifications for oscilloscopes in order to be able to catch the types of waveform anomalies discussed here.
