一种面向多供电模式的输电控制策略和能量传输频率优化算法

为了提高交流电源供电下充电信息能量传输效率,设计了一种面向多供电模式的输电控制策略和能量传输频率优化算法。建立了一个LC串联电路的具体模型,并利用傅里叶变换的方法来实现将线性系统的时域稳态特征转变成频域模型,构建了频域模型对物理过程对能量传输效率的各项影响因素进行分析。仿真分析得到:发生共振时电压源将会形成频率分叉的情况但电流源模式不会受到影响,经实际测试可知处于共振与电压源模式下都会发生频率分叉,得到跟模型预测相同的结果,验证了本算法的可行性。该方法对提高多供电模式下电控制系统的传输频率起到一定的理论支撑作用。

A transmission control strategy and energy transmission frequency optimization algorithm for multi-supply mode

In order to improve the efficiency of charging information and energy transmission under ac power supply, a transmission control strategy and energy transmission frequency optimization algorithm for multi-supply mode are designed. A concrete model of LC series circuit is established, and the time-domain steady-state characteristic of linear system is transformed into a frequency-domain model by means of Fourier transform method.Simulation analysis shows that: when resonance occurs, the voltage source will form frequency bifurcation, but the current source mode will not be affected. The actual test shows that frequency bifurcation will occur in both resonant and voltage source modes, and the result is the same as that predicted by the model, which verifies the feasibility of this algorithm.This method plays a theoretical support role in improving the transmission frequency of the power control system under the multi-supply mode.
