==Inhibitor==
* Harmonic distortion.
* High frequency duty cycle curse voltage unstable.
* Less flexibility of over load.


==Paradigm==
* The maximum power output is not that important any more. The efficiency η is going to take the place of leading the electronics products.
* “Less is more”, the quantity is not playing a major game any more. The quality will take the major position of the consumer electronics.
* Saving the energy. How to minimize the energy consumption and increase the functionalities? The percentage of the heat which is created by the voltage and current become more important.

==Timing==
* 1930: The published application of grid-controlled gas-filled tubes. (The mercury-arcrectifier and gas-filled thyratrons)
* 1930: The field-effect principle was first disclosed in U.S. patent by Julius Lilienfeld.
* 1947: The point-contact transistor was demonstrated by Walter H. Brattain and John Bardeen (Shockley 1972 & 1976), with William Shockley as an intensely interested observer.
* 1948: The invention of the bipolar junction transistor in 1948 was the beginning of semiconductor electronics. 
* 1948: Shockley and Pearson tried fabricating a rudimentary FET using evaporated layers of germanium on dieletric. 
* 1950: The semiconductor power diodes become available.
* 1957: The most popular member of the thyristor family - the SCR - was announced by General Electric, that semiconductor power electronics really began.
* 1969: The vertical V-groove MOSFET was published.
* 1970: The power FET development had spread worldwide with each year announcing a new technology.
