Tham khảo tài liệu 'chapter 16: power circuits: switching and amplifying', kỹ thuật - công nghệ, điện - điện tử phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | CHAPTER 16 Power Circuits Switching and Amplifying copyright 2002 Delmar Thomson Learning Objectives Describe and Analyze Efficiency MOSFET vs. BJTs Power switching circuits Classes of amplifiers Power amplifiers Heat sinks copyright 2002 Delmar Thomson Learning Introduction This chapter looks at circuits designed to deliver large amounts of power to loads. Efficiency is major concern in power circuits. Switching circuits are more efficient than the equivalent linear circuits. Different class amplifiers differ in efficiency Heat sinks are required to prevent the failure of semiconductors from excessive temperature. copyright 2002 Delmar Thomson .
