As a global leader in lighting, Philips has been working hard to transform the entire society into energy efficient solutions. Philips Lighting provides insight into the needs of the public and private spaces and is committed to delivering innovative, end-user-oriented, energy-efficient lighting solutions and applications. A few days ago, Philips further promoted green lighting, and specially sponsored the 3rd International Street Light Exhibition in Guangzhou, the China Urban Lighting Energy Conservation Summit Forum, and will publish a topic at the forum: Light up the “Green Road†to the future. Keynote speech. Promote green road lighting concepts and lead sustainable development.
Since lighting occupies 19% of global electricity consumption, the use of energy efficient lighting will greatly reduce worldwide energy consumption and reduce harmful carbon dioxide emissions. Philips offers advanced energy efficient solutions for all areas including roads, offices, industrial, entertainment and home lighting. In the construction of future applications and technologies for new lighting, Philips is also a leader, such as LED technology, in addition to high efficiency, it also has more advantages, and provides countless new, unprecedented lighting solutions.
Fast Recovery Diode (FRD) is a semiconductor diode with good switching characteristics and short reverse recovery time. It is mainly used in switching power supplies, PWM pulse width modulators, inverters and other electronic circuits as high-frequency rectifier diodes. Free-wheeling or damper diodes are used. The internal structure of the fast recovery diode is different from that of an ordinary PN junction diode. It belongs to a PIN junction diode, that is, a base region I is added between the P-type silicon material and the N-type silicon material to form a PIN silicon wafer. Since the base area is thin and the reverse recovery charge is small, the fast recovery diode has a short reverse recovery time, a low forward voltage drop, and a high reverse breakdown voltage (withstanding voltage).
