The  JD-BP series medium voltage fvariable frequency drive designed and manufactured by Advanced Electric Systems LLC.  has prominent performance and high reliability with low cost. It is of AC-DC-AC voltage type inverter with main loop of multi-level topology circuit. The control mode adopts SPWM technology. And the input uses isolated transformer of multiple technology, while the output is fulfilled by the solution of phase-shifting tandem multi-unit and medium voltage to  medium voltage direct conversion.

Many years of technical experience enabled Advanced Electric Systems LLC. and its staff to have developed inverters with low harmonic content, which is in a leading level in domestic. Perfect output voltage sine wave provides the inverter with stability of motor's operation during the whole speed regulation range. The low input current harmonics almost has no any disturbance to the grid and this ensures the operation reliability of the surrounding electric equipments.

This series inverter can drive and regulate the  medium voltage motor in almost all kinds of application area. The speed regulation is smooth, and the efficiency and power factor is enviable. In particular, nowadays the world is in short of energy. JD-BP variable frequency drive can bring great economic effect when used for blowers and pumps.

This series inverter consists of three main parts, transformer cabinet is on the left, and power unit cabinet is in the middle, while control cabinet is on the right. To improve the stability of the control circuit and to make the debugging more convenient, the control cabinet door was put on the right of the machine. This series product adopts cabinet structure with forced air cooling. And the big capacity machine adopts the cooling mode of water-cooled, air-closed circulation. The wiring terminal of input and output of the complete machine was placed on the lower left back. It is easy for connection.
