Foreword
MD series inverter is a new
generation of high-performance
modular inverter launched by
Shenzhen Inovance Technology Co.,
Ltd, which represents the future
development direction of the inverter.
Unlike traditional inverters, MD series
inverter creates a customized platform
through modular design and flexible
combination of multiple modules of
single series inverter based on
different customer requirements for
functions and performances.
MD series inverter creates three
new concepts in the future inverter
sector:
1. It firstly creates the three-tier
modular structure standard for new
generation of inverter as shown in
Fig.1.
2. It firstly makes the physical
standard for distinguishing the main
modules, such as motor drive, general
function and special function, from the
sub-modules as shown in Fig.2.
3. It leads the new industry trend of
popularizing the vector control
technology.
Such concepts will bring about
profound influences on the inverter
industry.
The modular structure is described as
follows:

Fig.1 Comparison between Traditional
Inverter and MD Series Modular Inverter
1) The bottom-layer module of the
MD series inverter is high-performance
motor control module and consists of
V/F, non-speed sensor vector control
(SVC) and vector control. It is mainly
responsible for high performance
control and overall protection of the
motor, controlling the motor through
sending running commands to multiple
channels or performing close loop
vector control through encoder
interface.
2) The middle-layer module of MD
series inverter is general functional
module, which mainly includes some
basic functions of the inverter, such as
PID control, MS speed, swing
frequency and other general functions.
According to the degree of complexity
of functions, Shenzhen Inovance
Technology Co., Ltd provides two
sub-modules for options of the
customers, namely, MD320 functional
module and MD300 functional module.
Refer to Table 1 for the difference
between the two modules.
