Previous section: PCB Layout for EMC, Part 2 Welcome to section, 3-3 of our Power Supply Design Tutorial. If you haven’t seen parts 3-1 and 3-2 yet, I strongly encourage you to do so. Since this ...

WBG transistors also switch faster and can operate at higher frequencies than silicon. Lower on-resistance means they dissipate less power, thereby promoting efficiency. This unique combination of ...

Impact of the semiconductor industry Nowadays, there is a strong focus on sustainability in semiconductor manufacturing. If we look at emissions across the entire supply chain across all sectors, we ...

GaN FET thermal calculator The use of the thermal calculator is easy and self-driven. The user starts by filling in the input parameters for the devices and the board/heatsink configuration. The ...

Class AB Amplifier The main class AB advantage is that it has the lowest distortion—total harmonic distortion plus noise (THD + N) is less than 0.1% for high fidelity. The main disadvantages are that ...

Aehr Test Systems disclosed that an initial customer order for a FOX WaferPak Aligner and a FOX-NP wafer-level test and burn-in system intended for gallium nitride power devices has been received. The ...

Figure 1 shows the most general scheme of a motor drive. The power converter generates regulated electric energy that is used to drive the motor, whose output is mechanical energy. Figure 2 represents ...
