Description
hardware flow control. It is an ideal choice in the field of industrial automation.
First, it has high power and is a fan/pump type load;
Second, the device itself has a power-saving function (software support);
Frequency converter (Variable-frequency Drive, VFD) is a power control device that uses frequency conversion technology and
microelectronics technology to control AC motors by changing the frequency of the motor”s operating
power supply. The frequency converter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC),
braking unit, drive unit, detection unit, microprocessing unit, etc. The inverter relies on the switching of the internal
IGBT to adjust the voltage and frequency of the output power supply, and provides the required power supply voltage
according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In
addition, the inverter also has many protection functions. , such as overcurrent, overvoltage, overload protection, etc
. With the continuous improvement of industrial automation, frequency converters have also been widely used.
Main applications of power electronics technology (classified according to applicable occasions):
1. Electronic control equipment for petroleum, coal and other mining industries;
(1) Main equipment: thyristor DC motor system; frequency converter and AC speed control system
(2) Market prospects: Non-renewable resources such as oil and coal are gradually declining, but I guess they will
continue to do so in the next few decades. As long as you need to dig for oil, coal, and gold… there will be a
market for power electronics technology
(3)Market size:
(4) Related companies: ABB, Siemens, Tianshui Electric Transmission Research Institute Co., Ltd.
(5) Recommendation index: Recommended (a total of 3 levels: not recommended, recommended, strongly recommended)
2. Electric vehicle field
(1) Main equipment: First, the equipment on the electric vehicle itself (controller, etc.), second, the charging pile, and third, the test system
(2) Market prospects: Due to the strong support of the Chinese government, the current electric vehicle market is quite promising.
(3)Market size:
(4) Related enterprises: vehicle manufacturers (Tesla, BYD, BAIC), charging pile manufacturers, power battery and other testing equipment (I am here)
(5) Recommendation index: Strongly recommended
3. Occasions with high power requirements, such as computer systems in banks and stock exchanges; key equipment
such as network servers and routers; various medical equipment; office automation equipment; factory automation machines, etc.
(1) Main equipment: UPS (uninterruptible power supply)
(2) Market prospects: It has matured and should continue to maintain steady growth in the next few decades.
