交-直-交电压型变频器主电路的原理图上元器件少,且分布直观。但在实际的电路搭建过程中如果任意组合或考虑不周,那么这样的系统是存有安全隐患的。
AC - DC - AC voltage inverter schematic of the main circuit less components, and the distribution of intuitive. But in the actual circuit construction process if any combination or ill-considered, then such a system is a potential safety hazard.
