[introduction] when can negative feedback turn positive and negative into make a present of? When should controlling an engineer to want to realize pretty good gain and phasic abundant to spend. Ben Bowen summarizes the 4th acting SiC FET how to be design personnel to offer ideal function chooses with a variety of parts of an apparatus, support taller design flexibility at the same time, realize the power with best cost effectiveness to design thereby.

Article of this rich guest is released by United Silicon Carbide (UnitedSiC) at first, this company joined Qorvo community in November 2021. UnitedSiC is a banner carborundum (manufacturer of SiC) power semiconductor, its affiliation makes Qorvo expand business electric car (protection of power source of EV) , industry, circuit, but the market of the rapid growth such as second birth the sources of energy and data center power source.

Feedback is a favour, control engineer hopes to receive negative feedback, and good gain and phasic abundant are spent, and the businessman prefers make a present of of positive and negative, for instance: The 4th acting SiC FET has UnitedSiC of class of client demand 750V more option. The Europe of 18 fine long hair of UnitedSiC and parts of an apparatus of Europe of 60 fine long hair hold lead position in the market, but in some application, lower resistance component and taller the watch intermediate has an advantage. This depends on specific application and budget, guide a resistor low-down is individual high-end SiC FET takes up the space is very little, assemble rise simpler also, but paralell connection of component of will low cost also can get guiding identically connecting resistor, and normally as much effective, especially a few come loose when hot space. However, this need paralell connection of parts of an apparatus, need more design works.

Series of the 4th acting SiC FET added more part

To realize this one flexibility, unitedSiC was rolled out guide electrify block is 23, the 33 the 4th acting 750V SiC FET with Europe of 44 fine long hair, and 6, 9 with component of Europe of 11 fine long hair, this is when make on the 18 with parts of an apparatus of Europe of 60 fine long hair foundations that already rolled out great improve. Nowadays, the client can be mixed according to its specific heating power operating mode moving condition undertakes mixture collocation, in order to achieve the optimal combination of the price and function, it is OK to be returned probably basis application demand more or less paralell connection component of a few low cost, make its apply to different design, enjoy the wholesale price of these low cost components thereby.

Shunt-wound SiC FET is very easy, and grid drive power is very low, make the additional power of shunt-wound generation nots matter normally. As a result of these parts of an apparatus guide electrify block is had temperature coefficient, so nature can come true to all flow, still have an additional relevant advantage in addition, namely with individual photograph of parts of an apparatus of Europe of 9 fine long hair is compared, always conduct loss of parts of an apparatus of two shunt-wound Europe of 18 fine long hair lower. Because be compared with photograph of individual parts of an apparatus,this is, these two parts of an apparatus had shed the electric current of the half each, the power of generation also has an in part only, the temperature rise of every parts of an apparatus is smaller also, and guide the amplitude of electrify block also can decrease in proportion. In addition, reduce lukewarmly as the knot, dependability can rise naturally also, it is thereby already very tall SiC maximum provides more abundant amounts. UnitedSiC is based on the FET-Jet calculator of the network to already rolled out the 2nd version now, the effect that the shunt-wound SiC FET that can be used at examining aleatoric quantity plays with moving condition in all sorts of application, provided the data of a few actual loss and temperature rise.

Graph 1: Competition is intense the UnitedSiC below the environment is brand-new series of 750V SiC FET adds a product newly

The 4th acting SiC FET still precedes for the industry technology

The new increase production of this series is tasted with old outstanding quality factor is had like having a product, used likewise advanced the 4th acting workmanship, for instance: The brilliant circle that can reduce base material to conduct loss decreases thin technology, and can realize lowest to written guarantee – housing thermal resistance and corresponding the silver-colored agglomeration grain with small lukewarm knot sticks outfit technology. These components use TO-247 3 to bring a foot to enclose, and when need uses source pole to open Er article to join, still can use 4 bring a foot to enclose. Graph 1 summary with SiC MOSFET competitive product photograph is compared, the advantage of new-style 750V SiC FET, and did not forget, the rated voltage of SiC MOSFET is 650V only.

Series of UnitedSiC 750V SiC FET offers more agile and extensive component alternative, can use at a lot of application. And accord with requirement of attestation of AEC-Q101 car class, because this can be used at drawing inverter, car carries and be not a car,carry charger, DC/DC converter and wireless charge, spend in order to realize the efficiency with ratedder than 650V higher component and voltage abundant. In AC and application of breaker of DC solid state, low conduct loss crucial to increasing efficiency and contractible size, because this exceeds low guide electrify block has fundamental value. Generally speaking, in industry and product of IT power changeover, the 4th acting SiC FET still can raise hard switch and soft switch develop to attack structural function.

Ask you to continue to offer feedback, unitedSiC already optimized annulus road compensation according to your demand, answer in order to come true quickly, offer more option.
