In addition to the presentation Francesco Muggeri replied to the media queries as below:

ELE Times: Does ST address the changing standards of Power and Energy and driving demand for semiconductor content in India? What market trends do you foresee in the next 2 to 3 years in the wake of changing standards of Power and Energy?
Francesco Muggeri: I think India is the next big country with huge demand for electronics. But it will come from a very different aspect because the demands, culture, population, habits and user experience of India are quite different from those of China, Korea, Taiwan, Southeast Asia Europe and America. In India, the problem you need to solve is not car electrification because car electrification means converting existing cars with gasoline engines to electric vehicles. In India, there are a lot of cars. But the problem that India needs to solve is electric mobility. Very often we see in India there is demand for two wheels high power electric vehicles and high power e-bikes, which are small vehicles driven by electric power. Tata manufacture, in the market today, small cars in India to satisfy this special market.
Now if you look at it from the charging point of view, or from the power and energy point of view, you will need very high power to charge small cars and e-bikes. If you look at the market today in which we are in contact with the customer, I see one of the most advanced market for electric bikes in India. How to charge these batteries with wireless power, not having any plug of cable? It require 120kW battery power on average to charge a car. But in India, we perhaps need only around 30~40kW. So the power solution is different. In addition, India is very big in size. It has a very extensive grid system and its population is very sparse. You cannot reach most of the villages easily. So as you see, we need to address it in a different way.
We have a big Indian team to address this. We have a lot of components such as SiC and GaN which we talked about today. We are trying to address solar market in India. Another aspect of differentiation is how we address the Indian market. We need to use the UPS in India. If you remember a few years back, one of the main problems you might have on UPS is the stability of the grid power. This has created a lot of failures, and therefore the computers were shutting down. So everyone here is adopting UPS to have continuous supply of power so as to avoid the shutdown of computers. Thanks to the continuous improvement in the grid power and UPS now. However, it is necessary to use UPS because you may run for 6 to 8 hours a day. So the kind of UPS you are seeing now are different, the kind of independent providers of energy are different.
In addition, the recent regulation in India has created an important boost for the local economy. The new norms require that, locally you have certain level of production of the integrated system, so many locally invested companies and all the other international companies in India are working with us to customize and develop solutions including home appliances that we are working with local companies to create locally needed appliances and other kinds of consumer products. So power management in India is something different. It is leading the world in terms of innovations, user experiences and particular needs.
ELE Times: How important is the motor control market beyond Air Conditions and fridge? What are the solutions for that market? What give you a leading edge over your competition?
Francesco Muggeri: In terms of home appliances, we also have washing machine, air dryer and dish washer solutions. Besides those home appliances, we also have appliances for restaurants, factories, food producers and food processing factories. Take air conditioning for example, when we are talking about its relevant industries, we are talking about conditions like heat, ventilation, and air conditioning, also the floor, the air, humidity, moisture in a certain way.
We can also move to motor control for e-bikes, professional drones, vacuum cleaners, professional power tools, and factory automation such as robots. When we go to robots, for example, we need high level of computation, because we need extreme precision which is made through high level of numeric computation. So automatic computation becomes fundamental. You also get the precision required to operate on medical equipment. So you have different requirements. After you go to the production line, you will also have high level of power requirement. When you move to the train and railways, you will have higher level of requirements on module. This makes it very fundamental and complex. The strength of ST is that it has very different technologies and can do systematic package. We have different variety of packages, and we are ready to collaborate with customers, then we are able to satisfy very fragmented markets. What we need is more flexibility and to speed up customer products to the market in time.
