... Therefore, (vCa)peak ≈ 196+6.85=202.85 V. Because the system is balanced, the peak value should be the same for all phases. The required dc voltage should be Vdc ≥ 2(vCa ) peak = 405.7 V for the triangular-wave PWM or Vdc ≥ 3 (vCa ) peak = 351.35 V for the space vector PWM. 2. The instantaneous real ...

Triode
A triode is an electronic amplifying vacuum tube (or valve in British English) consisting of three electrodes inside an evacuated glass envelope: a heated filament or cathode, a grid, and a plate (anode). Invented in 1906 by Lee De Forest by adding a grid to the Fleming valve, the triode was the first electronic amplification device and the ancestor of other types of vacuum tubes such as the tetrode and pentode. Its invention founded the electronics age, making possible amplified radio technology and long-distance telephony. Triodes were widely used in consumer electronics devices such as radios and televisions until the 1970s, when transistors replaced them. Today, their main remaining use is in high-power RF amplifiers in radio transmitters and industrial RF heating devices. The word is derived from the Greek τρίοδος, tríodos, from tri- (three) and hodós (road, way), originally meaning the place where three roads meet.
