Supporters such as digital controllers believe that digital power supplies are more adaptable and flexible than analog power supplies. Will the future be a one-sided trend? Supporters of material control have confidence in wide bandgap (WBG) devices such as gallium nitride (GaN) and silicon carbide (SiC) switching devices due to the demand for high efficiency and low power consumption, but there is some nerve damage in terms of price. ...... Although the cost of analog power solutions, performance (such as power response time when load changes), footprint and other indicators are better than current digital power solutions, but for developers looking forward to innovation, it is completely a kind The fixed-mode black box application suppresses the developer's passion for creativity. Digital power is proposed to overcome the complexity of modern power supplies. It combines digital and analog technologies, provides great adaptability and flexibility, and has the ability to directly monitor, process, and adapt to system conditions. Almost any power requirement. Digital power supplies can also be remotely diagnosed to ensure continuous system reliability for fault management, overvoltage (flow) protection, and automatic redundancy. At present, analog technology + DSP / MCU is becoming the main trend of digital power. According to a report from IMS Research, a research firm, IHS, it is estimated that the global digital power market revenue will increase to 12.4 billion US dollars in 2017, and the digital power IC market will reach 2.6 billion US dollars. The digital power market is dominated by server and communication device applications, and expanding to other applications is like a spark. Munich Shanghai Electronics Show as the opening ceremony of the electronics industry, in March 2017 there will be many leading power chip companies such as Toshiba (Booth No. E4.4300), Roma (Booth No. E4.4100), STMicroelectronics (Booth) No. E4.4102), Linear Technology (Booth No. E4.4401), Core Source (Booth No. E4.4112), BYD (Booth No. E4.4512) and other collective display power management chips. Major power management IC manufacturers are rushing to meet the demand for digital power market. 2017 Shanghai Shanghai Electronics Show Pavilion layout The digital controller's loyal supporters use digital power management because digital power supplies provide accurate information about the power system and can easily control and monitor dozens of voltages autonomously. Manufacturers offer custom and affordable devices for specialized markets, making it easy for novice and experienced digital power designers to use. The LTC2944 multi-cell battery monitor recently offered by Linear Technology (Messe E4.4401 at the Shanghai Electronics Show) is one of them. The LTC2944 can be used to directly measure 3.6V to 60V battery packs. Level shifting circuitry is absolutely not required on the power and measurement pins to connect multiple battery voltages, thus minimizing total current consumption while maintaining measurement accuracy. The LTC2944 is a true high-voltage battery monitor that measures charge, voltage, current, and temperature with 1% accuracy. These parameters are essential to accurately evaluate battery charge status (SoC). 60V battery monitor for multi-cell battery systems Digital power meets the design engineer's need for flexible, intelligent and convenient power management. The emergence of wireless power allows users to get rid of the constraints of cables and provide more convenience. Forecasts from professional organizations: By 2018, global wireless power receiver shipments will reach 1 billion. ST's leading semiconductor supplier ST STMicroelectronics (Messe Munich Electronics Show Booth No. E4.4102) provides a total solution through built-in transceivers, supporting multiple industry standards and terminal power supply standards such as Qi and PMA, including the Internet of Things. Products, mobile phones, wearables, power tools, automotive and medical grade power supplies. STMicroelectronics recently introduced the STWBC-WA charging transmitter controller with the STWLC04 wireless charging receiver, using smaller coils than the coils used in other wireless charging chipsets on the market, using only 11mm diameter coils at the receiving end, at the transmitting end. With a 20mm coil, it can transfer up to 1W of power, making the appearance of the application device smaller and slimmer. If large coils and full-bridge circuits are used at the transmitter, the transmission capacity can be increased to 3W. Because traditional charging interfaces are no longer needed, wireless charging simplifies housing design and sealing technology to prevent dust or moisture from entering the machine. STWBC-WA Charging Transmitter with STWLC04 Wireless Charging Receiver In addition, it is worth noting that with the global awareness of energy conservation and environmental protection, the power industry has begun to invest in technology development to improve product efficiency, reduce power consumption and reduce material use, plus electric vehicles, renewable energy and various energy transmission and conversion systems. High efficiency and low energy consumption are required to make high-performance power components such as SiC and GaN with superior performance. In order to achieve efficient energy transmission and utilization, these high-performance power components play an important role in energy conversion. Traditional Si-based materials cause a large amount of energy loss during power transmission or conversion because they do not provide a low on-resistance. SiC components are resistant to high voltages and high currents due to their high thermal conductivity and wide energy gap characteristics, which is more suitable for high temperature applications and energy efficient applications. Rom Semiconductor (Munich Shanghai Electronics Show Booth No. E4.4100), which has been the industry leader in SiC power devices, has 2nd, 3rd generation SiC-MOSTET and full SiC power module products with high-speed switching and low switching loss. High-speed recovery, eliminating the problem of component degradation caused by parasitic diode energization. ROHM full SiC power module Although the advantages of SiC are full, the current size of the SiC market is less than 10% of Si compared to Si products. Why? Suwon Dejian, senior manager of the discrete components division of Roma Semiconductor (Shenzhen) Co., Ltd., pointed out that the biggest limitation is the higher price. In order to reduce costs, several improvements are needed: First, in development, try to make the wafer bigger, because the larger the wafer, the die/chip (chip/chip) that can be obtained on each wafer. The more it is, the less waste is. The second is to improve the production efficiency of the factory. The production time of SiC is very long. Because SiC is Si plus C, the production time is about 6 times that of ordinary Si. Third, I hope that the amount of the market will increase, and the higher the dosage, the lower the unit price will be. In 2017, did the market price of SiC drop? How does it perform in the first large-scale solar PV (PV) inverters and the hot new energy vehicles (EV/HEV) market? On March 14-16, the Shanghai Shanghai Electronics Show unveiled everything! Compared to SiC, GaN power components are a rising star. However, it has been widely used in LED lighting and plays an increasingly important role in wireless applications. GaN-based switching power transistors enable new power applications, compared to Si transistors: higher performance and lower losses when operating at high voltages; GaN's high-frequency operating characteristics can improve performance while maintaining high efficiency. These advantages will enable GaN to first take its place in higher performance power supply designs to meet customer requirements for more efficient power conversions. According to the research firm Yole's prediction, the GaN power market is moving toward integration and is ready to face tremendous growth. "The GaN component market is expected to reach $600 million by 2020, when it will need to manufacture 580,000 6-inch wafers. In addition, the GaN market will grow rapidly in 2016, along with electric vehicle (EV)/oil-electric hybrids. The vehicle (HEV) will begin to adopt GaN in 2018-2019, and an estimated 80% CAGR growth by 2020. Fujitsu Electronic Components (Shanghai) Co., Ltd.
