In this study, a three-phase, 10-kV DC, 50-Hz, modular multilevel converter is designed in PSCAD environment by using 10 sub-modules in each arm. For each submodule of the designed converter, half ...

In this article, we propose a voltage-controlled oscillator (VCO) with a single three-coil transformer, featuring a common-mode (CM) resonance expansion and intrinsic differential 2nd harmonic output.
