Modern power began in the late 1950s and early 1960s rectifier technology, its development has gone through the rectifier times, the times and frequency inverter era, the power to promote the emerging field of technology in many applications. The late 1980s and early 1990s developed the power MOSFET and IGBT as the representative set of high-frequency, high voltage and high current in a complex power semiconductor devices, that the traditional power supply technology has entered the modern era of emerging technology. Modern power technology trends: (2)modular, intelligent. Modular power supply technology, including power unit and output unit modular modular. New switching power supply to the power switch and protection modules integrated with a variety of output, so that further reduce the size of switching power supply. Output voltage regulator circuit modular, so that power in practical applications more flexible, convenient and smart. (3)figures, and diversification. With the development of digital technology and mature, more modern power supply to the digital direction. Using digital technology can reduce power high-frequency harmonic interference and nonlinear distortion, while allowing CPU digital control. Modern power supply with good EMC characteristics, self-generated high-frequency harmonic power decreases, reducing the environmental "pollution", while enhancing power in itself anti-jamming performance. 2 Types of power supply Classified according to the state input-output: AC-AC, AC-DC, DC-AC, DC-DC. Classified by work status: a linear power supply, switching power supply, diode power supply. Regulator with load connected by way of classification: the series-type power supply, a shunt regulated power supply. Output voltage adjustment by way of classification: fixed output power supply, adjustable power. With the power technology development, classification and definition of power has become increasingly blurred. For example, LA76810 AN5265 TV receiver integrates audio amplifier using 9 V DC power supply, while the television receiver is not using direct output or 9 V DC output voltage regulator block 7809, but by 7812 after the 9 V output voltage regulator diode and to the IC power supply. For fixed and adjustable power supply, 78 series and 79 series are commonly used in electronic engineer fixed output voltage regulator IC, 317 and 337 are commonly used adjustable voltage output integrated circuit. Now 1085 is a 3.3 V output can also be a 1.7 V output, simply by changing the external circuit resistance. Switching power supply for its small size, high efficiency, PWM control loop, the output short-circuit and overload protection features have been occupied by the power market, linear power supply has been completed mission, and gradually fade into history. |
