From page 191...
... . Because the power semiconductor devices used in power electronic circuits operate as switches, they ideally carry zero current when they are off, and support zero voltage when they are on.
From page 192...
... The IGBT can switch at maximum frequencies in the 50-100 kHz range, while the power MOSFET can switch at frequencies in the 10's of MHz range for silicon based devices, and in the 100's of MHz for devices fabricated in gallium nitride (GaN)
From page 193...
... The thermal constraints of passive components also are currently an obstacle to decreasing the size and weight of power electronics, suggesting that development of high temperature materials for passive components could enable hotter power electronics, thereby improving fuel efficiency by reducing cooling system losses. Commercial work in this area may not be adequate for the Army's needs due to commercial application cost constraints.
