As the whole nation and even whole world the section can decrease the further development of the platoon, what high-pressured transducer product has made electric power trade is new bestow favor on. The wind report of our country reachs all sorts of large development, need as market place, appeared the new show of a lot of industries. Although the high-pressured transducer product of Ming Yanglong source has a few years only, on the world before using order compositive the technology such as strong IGBT of degree of tall, dependability, IGCT. Having on product of high-pressured frequency conversion in the market extensive apply actually, acquired better market share, also got an user approbate. Product of transducer of two high pressure is recommended below.
System of frequency control of MLVERT-D series high pressure
Use high pressure to be inputted directly, through module of low-pressure IGBT power series connection technology realizes high pressure to be outputted directly, have power input factor tall, harmonic is small, output weaveform approachs the good point such as standard sine wave.

Technical characteristic:
1. is tall - high structure, 3kv/6kv/10kv is outputted directly, do not need to output a step-up transformer. Output is PWM of type of transpose of unit series connection
2. control system is used " odd a screen of machine PLC feeling " plan, systematic reliability is high, complete reliability is high, put an end to the memory attaint that labour dominates aircraft program and appears, fan completely to stop the breakdown such as carry.
The voltage abundant amount of 3. power parts of an apparatus is large. The product of 6KV voltage grade, what Ming Yanglong source uses is 1700V parts of an apparatus the plan that 6 class module establishs ties, voltage of its power parts of an apparatus makes rich the quantity is 2.1 times; The 1700v parts of an apparatus that domestic and international other manufacturer uses 5 class module establishs ties (or 1200V parts of an apparatus 7 class module establishs ties) plan, voltage of its power parts of an apparatus makes rich the quantity is 1.7 times only.
4. power module uses an input solely to insert in home unplug means, insert the product that unplugs component uses Shinaidesheng to produce, use junior line means, below the premise that assures dependability, simplified field assembly, maintenance workload, shortened greatly field assembly, defend time, change a module needs the left and right sides 2 minutes only.
Ark of 5. power module uses junior wind means, transducer front door is added outfit increase viewport, observation of moving circumstance of module of transducer interior power is direct, be clear at a glance.
