They did not consider the physical processes of the development of resonance overvoltage on even harmonic
components, although the occurrence of this type of overvoltage is known for a relatively long time.
From the internal interaction, SPVSC will generate a series of odd harmonic currents on ac side and a series of even harmonic
voltages on dc side.
This phase error contains DC and even harmonic
Actually, the MFD and the MMF should have each odd harmonic component ; therefore the square operation in (5) will generate each even harmonic
component, with the amplitude in inverse proportion to the harmonic order.
More specifically, can the odd harmonic series be different from the even harmonic
2.In this investigation observed that, the harmonic spectrums contain only odd harmonics because there is symmetry present between positive and negative half cycle, even harmonic

double-balanced active mixer for use in direct conversion receivers," IEEE J.
Those measured results include only the fundamental and the third harmonic components, while the second harmonic component cannot be detected because the even harmonic
components circulate within the loop formed by the two anti-paralleled diodes .

Mixer for Direct Conversion Receivers," 2000 International Symposium on Circuits and Systems Digest, pp.
The value of even harmonic
order can be concluded as 2nd order is the highest followed by 4th order and 6th order, respectively.
Additionally, when a capacitively terminated [lambda]/4 bias line is connected to the signal path, the even harmonic
frequency components of the fundamental are blocked, but the odd harmonic components are transmitted.
In order to increase maximum efficiency up to 88.4 percent, it is necessary to provide a short-circuit termination for all even harmonic
voltage and an open-circuit impedance for the third-harmonic current.
