A non-professional interpretation of "Power Electronics Technology"

A non-professional interpretation of "Power Electronics Technology" [Copy link]

Today is September 2nd.

Design, modeling, material selection, layout, assembly, testing, and maintenance are technical jobs and the job of engineers, but the way I take is to seek knowledge, to observe the phenomena, to understand the essence, and to know the reasons. Therefore, I have no expectation that everything I post on the forum can gain consensus among you readers.

Is there a difference between electronic technology and electrical technology? If so, where is it?

The power level, the presence or absence of active devices (and their types), nonlinear dynamics, and more...,

Active devices can be said to be the soul of electronic technology. Power electronics technology is aimed at the "product" of power supply, electricity, and performs the function of regulating and modifying during the transmission process.

Vacuum tubes cannot function without high voltage. Thyratrons are active devices after all, and they handle the powerful mains electricity. Semiconductor diodes and thyristors are also used in the electrical field today. The magnetic saturation transformer, which also has a voltage stabilization function, is a nonlinear application, but it belongs to the field of electrical technology.

Is the thyristor inverter outdated? The first megavolt-level DC transmission project in China used it. SVC also used thyristors, which have not been replaced by APFC. Is the dimming of incandescent lamps considered a household appliance or a power electronics technology? So, is there an objective or universally recognized boundary between electronics and electrical? !

There should be no objection to the classification of UHV DC transmission projects as power electronics technology.

Inverter technology has entered the field of home appliances in recent years and is widely used in air conditioners and washing machines, and even in small appliances such as fans, hair dryers, vacuum cleaners, and blenders. As for razors and electric toothbrushes, there is no need to use them.

I think the definition of electronic technology is related to the use environment. The power carried by the transmission tower of a public broadcasting station ranges from close to kW to MW (1MW = 10mW), but in terms of the sector, it is broadcasting communication engineering rather than power electronics technology.

78/79 Voltage stabilizer integrated blocks or self-assembled electrical appliances with discrete components are ostensibly for load service, but aren’t the objects of regulation also electricity? If I add it to a pocket radio or a portable speaker, does it count as power electronics technology? Perhaps not, but those voltage stabilizers or electrical appliances are power electronic components and power electronic equipment. Be it components or equipment, aren’t they all power electronic applications? !

电源是甚么，电源，就是以非电能量驱策电子流动的换能器，

Distribution stations and transformer substations process the product of power supply, that is, electrical energy. They are not departments within the power plant, nor are they part of the power generation system.

「电源供应器」是甚么梗，是PowerSupply的直接翻译吧，可是，电源本身才是个「功率提供者」嘛，而PowerSupply的位置，相当于 变电配电站，角色是 沟通电源与负载的桥樑，作用就是 调控修饰，可视之为「有源导线」，或者是电源的外挂，

Control, just two words, are concise and comprehensive. It covers voltage stabilization, current control, frequency conversion, power factor correction, manual and automatic control. These methods are aimed at electricity. So I think that "power controller" is the most appropriate name in the world. The power supply itself is a supplier rather than a regulator!
