中文摘要:
      传统交错并联Boost PFC电路的平均电流控制法基于均流控制,但实际应用中无法确保元器件的参数一致,无法实现均流控制;针对上述问题,提出了占空比分配法实现交错并联Boost PFC的均流,该方法将总电感电流平均值的1/2与各相电感电流平均值进行比较,根据比较后的结果确定各相的占空比;通过对电路各元件参数的计算,实现了400 V/200 W交错并联PFC电源的设计;最后,利用MATLAB进行仿真验证,仿真结果表明,所提出的占空比分配法能够实现输入功率因数高和两路电感均流。
英文摘要:
      The average current control method of the traditional interleaved parallel Boost PFC circuit is based on current sharing control, but in practical applications, it is impossible to ensure that the parameters of the components are consistent, and the current sharing control cannot be realized. In view of the above problems, a duty ratio method is proposed to realize the current sharing of interleaved parallel boost PFC. In this method, 1 / 2 of the average total inductance current is compared with the average inductance current of each phase, and the duty ratio of each phase is determined according to the comparison results. The design of 400V / 200W interleaved parallel PFC power supply is realized by calculating the parameters of each component of the circuit. Finally, Matlab is used to verify the simulation. The simulation results show that the proposed method can achieve high input power factor and current sharing of two inductors.
