From the sun to the grid through efficient and smart semiconductors Semiconductors enable the game-changing in solar applications ……Semiconductors can help slow down the “unstoppable force” by reducing the amount of power used by products and making the generation and distribution of electrical energy more efficient. Semiconductors also enable technologies like smart metering and smart grids that help change the energy consumption patterns of consumers. Our industry can also have a profound effect on the “immovable object” by using our expertise in silicon technology, electronic circuitry and system architecture to make renewable energy sources more efficient and attractive to consumers. 2 ST’s positioning in the photovoltaic world • HV Converters • PWM controller + HV power MOSFETs • Protections • Photovoltaic ICs Solar battery charging
