多电平逆变器是当前高压大功率电能变换领域中的研究热点之一,它通过对直流侧的分压和开关动作的不同组合,实现多电平阶梯波输出电压,能有效地减小器件承受的电压应力,缩小装置体积,减小输出电压谐波和开关损耗。 - High - frequency link power converters are receiving increasing attention . when the input frequency of ac - ac converter is quite high , such as 20khz or above , in order to make sure the converter switching action is restricted to the zero crossing point of the link voltage , the switching cycle becomes discrete pulse spectrums , however , the conventional pwm converters are ruled out because they would fail either to the efficiency or the low - distortion criteria
当交-交变频器的输入频率非常高，通常为20khz时，为了在零电压条件下实现逆变器开关管的通断，变换器的开关时刻必须选择在高频交流电压脉冲为零时，这意味着变换器开关时刻在时间轴上成为不连续的点，而常规的硬开关pwm变换器是将开关时刻选择在任意时刻。 - Although dm can also solve the modulation time error , but the output waveforms can ’ t reach the industrial standard ( total harmonic distortion thd ) . considering this , a new control strategy called current optimal control ( coc ) is presented in paper . coc is that system samples the output value real time , comparing with expected value , considering all switching actions available then draw a concluding to decide which way would be fastest and best way to render system smooth
针对这一缺点,本文提出了一种更好的控制策略,电流最优delta调制,它是在电流滞环控制的基础上,根据电路的输出信号来分析,考虑所有可能的逆变器动作来决定选用哪一种开关转换方式能最快最平稳地达到预期值,采用的是一种电流预测控制手段,从而使输出波形的纹波最小。 - Continuous - time filter needn ’ t a / d switch , data processing , d / a switch technique and so on to finish filtering function with analog signal like digital filter . and it needn ’ t switch action to sample data in the discrete time with analog signal like switched capacitor filter . so continuous - time filter has several advantages , such as high processing speed , simple circuit configuration , and low power consumption
