CQ Publishing Wide gap semiconductor research

With the unstoppable development of electronic devices, the amount of electricity used is steadily increasing. Energy saving is eagerly needed in all electronic devices. In this series, we will approach electronics technology from the perspective of dealing with energy. Specifically, it deals with power supply circuits, power generation, power conversion, motor drive, lighting, etc. We will introduce technical information on electronics that are friendly to the global environment. The spread of SiC / GaN semiconductor power devices that breaks the limits of Si is imminent! Special feature Wide-gap semiconductor research (new wide-gap semiconductors will change the world Importance of semiconductor devices for power electronics: Applications as switching elements Performance index of semiconductors for power electronics from the viewpoint: To understand the operating principle of power devices Basic knowledge of semiconductor devices: The most important performance index of power devices Trade-off between withstand voltage and on-resistance, etc.) GE Articles ( Silicon carbide semiconductor application Audio amplifier made with SiC JFET: LLC controller IC PLC810PG with PFC function that can realize high efficiency and low noise power supply circuit: Prevention of forgetting to turn off, overcurrent detection by octopus foot, standby power check Waste reduction Three power consumption meters with visible effects)
