Abstract


Electronic ballasts as fluorescent lamps start properly and stable work indispensable accessories, is also an important way to save electricity for lighting . As energy and environmental protection issues have become increasingly prominent , the section of the source emission reduction has become the consensus of the world , so the development of high-performance electronic ballasts without delay . In this thesis, the design ideas from the circuit CAD Institute of Xidian University research project \This paper outlines the basic composition and working principle of the electronic ballast , electronic ballast inverter circuit topology and control method and a detailed analysis of the operating characteristics of the output of the resonant network . Select system solutions to develop the circuit functionality and performance indicators , designed a self-oscillating half-bridge driver the inverter controller chip XD3168 . The chip uses a high voltage LDMOS and CMOS compatible high-voltage integrated circuits (HVIC) technology , the high-voltage and low-voltage control circuit is integrated on the same chip , so that in terms of weight , price , and volume are greatly reduced . The chip self - oscillation , the oscillation frequency can be set by external components , the oscillation frequency range is the range of 20 kHz to 100KHz . To ensure the totem pole output power devices can be safely work without direct phenomenon occurs with a typical value 1.1μs deadtime . In addition , the internal integration of the bootstrap circuit , so that a higher degree of integration of the chip . Advanced floating supply mode , the ability of the high voltage of 600V . This circuit can be used in the high-frequency switching power supply, high frequency electronic ballast . The chip the XD3168 with the peripheral devices with the completion of the basic electronic ballasts to control ignition and normal fluorescent lamps work . Using the Cadence simulation software , based on the ultra-high pressure 600V 0.5μm BCD process on the chip XD3168 simulation different model , supply voltage, and temperature combinations . Simulation results show that the good performance of the design of the chip satisfy a predetermined design requirements .
