【摘要】：对于采用交错并联磁集成技术的三通道升压变换器中的耦合电感器对称化的设计是一件困难度较大的工作,基于脉宽调制技术调制的基本理论,本文选择占空比在D2/3的工作条件下,对三通道升压变换器的各个模态里的静态等效电感、瞬态响应速度等方面进行了研究分析,运用理论依据和数学计算验证了变换器在D2/3的条件下能够实现最优化的控制目的。所以本文通过研究三通道Boost变换器的交错并联磁集成理论和PWM技术与DSP数字控制相结合的控制方式来完成这项工作。首先,推导了占空比D2/3时三通道交错并联升压变换器中采用磁集成技术制作的电感在不同工作模态下的等效电感表达式,并且分析了该磁耦合电感的静态特性与瞬态特性,进而证明三相对称化耦合电感的优点。其次,提出两种不同的设计方案,对三相“EI”耦合电感器进行电感值对称化的设计,并通过量化计算与仿真实验对比两种不同设计方案的优劣,最后确定更为精确的方案进行三相“EI”耦合电感器实物设计。最后,根据更优的设计方案对三相对称化“EI”形耦合电感器进行实物制作与测试并将其用在三通道交错并联升压变换器上,通过运用仿真实验与DSP数字控制的样机电路实验对本文理论分析的正确性以及所设计磁件结构的可行性进行了验证。
[Abstract]:The design of coupling inductor symmetry in three-channel boost converter using interleaving parallel magnetic integration technology is a difficult work, based on the basic theory of pulse width modulation. In this paper, the static equivalent inductance and transient response speed of three-channel boost converter are studied under the condition of duty cycle at D _ 2 / 3. The theoretical basis and mathematical calculation are used to verify that the converter can achieve the optimal control purpose under the condition of D 2 / 3. So this paper studies the interleaved parallel magnetic integration theory of three-channel Boost converter and the control mode of PWM technology combined with DSP digital control to complete this work. First of all, the equivalent inductance expressions of the inductor made by magnetic integration technique in the duty cycle D2 / 3 three-channel staggered parallel boost converter are derived, and the static and transient characteristics of the magnetically coupled inductor are analyzed. The advantages of three-phase symmetric coupling inductors are proved. Secondly, two different design schemes are put forward to design the inductance value symmetry of the three-phase "ei" coupling inductor, and the advantages and disadvantages of the two design schemes are compared by quantitative calculation and simulation experiment. Finally, a more accurate scheme for the physical design of the three-phase ei coupling inductor is determined. Finally, according to the better design scheme, the three-phase symmetrical "ei" coupling inductor is fabricated and tested and used in the three-channel staggered parallel boost converter. The correctness of the theoretical analysis and the feasibility of the designed magnetic structure are verified by using the simulation experiment and the prototype circuit experiment of DSP digital control.
