Traction inverters are the main battery drain components in electric vehicles (EVs), with power levels up to 150kW or higher. The efficiency and performance of traction inverter directly affect the driving range of electric vehicle after a single charge. Therefore, in order to build the next generation of traction inverter systems, silicon carbide (SiC) field effect transistor (FET) is widely used in the industry to achieve higher reliability, efficiency and power density.

The current in an electronic circuit usually has to be limited. In USB ports, for example, excessive current must be prevented to provide reliable protection for the circuit. Also in the power bank, the battery must be prevented from discharging. Too high discharge current results in too large voltage drop of the battery and insufficient supply voltage of downstream devices

The NCP51820 is a 650 V, high-speed, half-bridge driver capable of driving gallium nitride (" GaN ") power switches at dV/dt rates up to 200 V/ns. The full performance advantages of high voltage, high frequency and fast dV/dt edge rate switches can only be realized if the printed circuit board (PCB) can be properly designed to support this power switch. This paper will briefly introduce NCP51820 and the key points of PCB design of high performance GaN half bridge grid driver circuit using NCP51820

In an increasingly interconnected world, we are increasingly relying on a wide range of electronic instruments and devices, as well as the semiconductors they contain. As a result, it is not surprising to see demand higher than ever for components capable of managing electromagnetic interference (EMI) and radio-frequency interference (RMI) in the radio spectrum.

Signal relays are essentially electrically operated electromechanical switches used to control the current in a circuit. A relay uses a magnetic force generated by a control current passing through a coil near a contact to move an internal moving part or contact between the pull and open positions. In this way, small signals can be controlled by large signals. A surname.
