Introduction to switching power supply

Low-power switching power supplies are widely used in many electronic products such as measurement and control instrumentation, communication equipment, learning and entertainment, etc. with their many excellent properties. With the increasingly prominent environmental and energy issues, people continue to increase environmental requirements for electronic products and pay more attention to the energy efficiency of electronic products. Designing pollution-free, low-power, high-efficiency green mode power supplies have become a hot spot in the research of switching power supply technology.

Basic structure of switching power supply

All things must follow the law of conservation of energy, and switching power supplies are no exception. In fact, switching power supplies are also completed by energy transfer. From the energy point of view, switching power supply can be divided into DC switching power supply mode and AC switching power supply mode. DC switching power supply mode mainly outputs DC signal power, while AC switching power supply mode mainly outputs AC signal power. The DC switching power supply mode is the current mainstream model.Control circuit and control circuit and other modules.The AC and DC input voltage is passed through the LC filter, then the bridge rectifier and the bus electrolytic capacitor are smoothed into a DC voltage, and then converted by the DC/DC converter, and then filtered by the diode rectifier and electrolytic capacitor to the output, in order to enable the circuit It becomes a closed-loop operation, and a control circuit is drawn at the output terminal, and then the amplifying circuit is transferred to the ratio control circuit to the DC/DC converter to form a closed loop. The expression method of duty ratio in the duty ratio control circuit.

1.2 Defects of traditional switching power supply

Traditional switching power supplies basically use traditional circuits. Most of the circuit chips used in traditional circuits are PWM-controlled KA38 series chips. Among them, switching MOSFETs are also used, and a startup resistor is also added. P=U*U/R shows that the standby power consumption of the circuit must be at least 0.5W, and low power consumption requires standby power consumption at least 0.5W, and some even less than 0.3W. For dense China, the power loss is undoubtedly huge. In addition, there are certain hazardous substances in traditional power supplies. According to the “Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment” in my country’s CCC standards, the environmental protection function has not been achieved.

1.3 Development direction of green switching power supply

Due to the many shortcomings of traditional power supplies, for the effective use of energy, people have proposed green switching power supplies. Green switching power supplies mainly focus on high frequency, high efficiency, low power consumption, miniaturization, integration, modularization, and intelligence. High reliability, meeting EMC standards and environmental protection, and many other directions continue to develop. Since the key technology of light, small and thin switching power supply is high frequency, major foreign switching power supply manufacturers are committed to the simultaneous development of new and highly intelligent components, especially to improve the loss of secondary rectifier devices, and to improve the power ratio. Fer rite (Mn Zn) material manufacturers increase technological innovation to improve the magnetic performance obtained at high frequencies and high magnetic flux density (BS), and the miniaturization of capacitors is also a key technology.
