变频器输出为PWM波，含有较多的高次谐波。变频功率传感器通过对输入的电压、电流信号进行交流采样，再将采样值通过电缆、光纤等传输系统与数字量输入变频功率分析仪，数字量输入变频功率分析仪对电压、电流的采样值进行运算，可以获取电压有效值、电流有效值、基波电压、基波电流、谐波电压、谐波电流、有功功率、基波功率、谐波功率等参数。
就国内变频器市场格局而言，业内人士将其概括为，变频器通用领域内资企业占据80%以上的市场份额，竞争激烈导致10年价格大幅下滑;高性能市场仍以外资品牌为主，未来将成为国内变频器企业的主攻方向。是国内智能化电气研发、生产和销售的为一体的高新技术企业。生产变频调速器、电机软起动器等工业自动化控制的厂家，产品采用重载型设计，过载能力强，具有超大起动和运行容量、完善的自动检测、保护和控制性能，可以起动和控制任何类型的重型负载电动机，产品已广泛应用于冶金、矿山、造纸、化工、建材、机械、电力、以及建筑系统等所有工业传动领域。
