Semi-solid electromagnetic stirring product introduction @hot sell

                AC- AC variable frequency               1. Because AC-AC Frequency Inverter has no middle dc link, just after one transformation of electrical energy, the efficiency is higher than the average frequency converter.        2 . Energy consumption is small, high conversion efficiency, and can use the thyristor to natural turned to.        3. The output frequency is lower than the AC supply input frequency, the output waveform is better. AC-AC frequency converter is especially suitable for application in high power, low speed communication speed regulation system.                             AC-DC-AC frequency conversion (Four quadrant vector control structure)     1. It can realize nets side unit power factor and sine wave current control. In ideal state double PWM inverter power input current is the input voltage and the same phase sine wave, power factor close to 1, the input current harmonic content is close to zero.   2. PWM converter can run in rectifying and inverter two kinds of state, can achieve energy bidirectional, effective use of renewable energy.   3. With excellent output characteristics, especially fast dynamic response.   4. It is energy efficient, quick adjustment, auto-balance etc. and also can be overcome by the thyristor rectifier of a communication existence fault circulation hidden trouble.
