12.16 Harmonic Amplification

Consider the capacitor switching that is illustrated in Figure 12.10. When the capacitor is switched on, the bus voltage can be expressed as

V c = V bus ' = j X C Z s j X C V S ( 12.77a )

or

V c = V bus ' = V s 1 ω 1 2 L s C+j ω 1 2 C R s ( 12.77b )

Capacitor switching.

At the resonance,

ω r = ω 1 h r = 1 L s C ( 12.78 )

or

h r = ω r ω 1 = 1 ω 1 L s C = X c X s = MV A sc M var c ( 12.79 )

Hence, the hth harmonic capacitor voltage (or the capacitor ...
