查询词典 electric current

The square wave or corrected sine wave auto inverters have many limitations. When supplying to inductive load (such as electric fan, electric drill etc.), a square wave or corrected sine wave auto inverter produces too much harmonic current which makes the load seriously heated and even damaged. When supplying to capacitive load or rectificative load such as notebook PC, mobile phone charger etc.
