Description: The most basic form of power: DC, AC
Four basic state transitions:
DC → AC, DC → DC, AC → DC, AC → AC
• power electronic devices just work in two states
Opened, shut-off
Opened: that operates in highly saturated conduction state
How to use power electronic devices on and off two states achieve energy transitions between the four basic power electronics is the core content to be studied
