Recently, across multiple electronic applications, the world's leading supplier of semiconductors, power chip maker STMicroelectronics (STMicroelectronics, called ST; NYSE: STM) introduced a new automotive quality grade silicon carbide (SiC) diode to meet electric cars and plug-in hybrid (PHEV, Plug-inHybrids) and other new energy vehicles on-board charger (OBC, on-boardbatterychargers) handle the demanding requirements of high-power within a limited space.These diodes allows designers to develop smaller power supply module, which is not only beneficial to the automotive power systems, but also to become a key choice to overcome Google and inverter miniaturization challenges raised by the IEEE. Google invested $ 1 million bonus up to collect smaller than one tenth of existing inverters, and for a variety of applications, especially solar micro-generator (solarmicro-generator) of kilowatt inverter design; STMicroelectronics Semiconductors are partners of the public challenge.The new diode using advanced technology to prevent large pulse current (high-currentspikes) burn unit. For security reasons, designers are still over-use of diodes. STMicroelectronics to develop new products completely changed the situation, overcurrent value is 2.5 times the rated current value, so designers can choose a smaller, more economical and reliability and energy efficiency will not be affected by the current smaller diode.
