摘　　要：为提升DC/DC变换器的整体性能,满足现代电源应用对体积、性能、效率和重量的要求,经过原理上的论证,设计一种零电压谐振控制器。控制器电路采用商用4.0μm40V高精度双极工艺完成整体设计,电源电压的工作范围为12~20 V,并具有较为合理的工作频率范围和输出驱动短路脉冲电流。在芯片内部设计控制电路以及保护电路,并采用固定关断时间控制方式和双路互补输出结构,实现软开关功能。经仿真实验,结果表明此款零电压谐振控制器电路满足设计要求。In order to improve the overall performance of DC/DC converter and meet the requirements of modern power supply application for volume,performance,efficiency and weight,a zero voltage resonant controller is designed after principle demonstration.The controller circuit is designed by commercial 4.0μm 40V high precision bipolar process.The working range of power supply voltage is 12~20 V,and it has a reasonable working frequency range and output driving short circuit pulse current.The control circuit and protection circuit are designed in the chip,and the soft switching function is realized by using fixed off-time control mode and dual complementary output structure.The simulation results show that the zero voltage resonant controller circuit meets the design requirements.
