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.
