This is likely to drive the demand for high voltage
amplifiers from the medical sector.
The PMSG voltage
equations are illustrated in (3), where [R.sub.s] and [L.sub.s] represent stator resistance and inductance, respectively.
'The CONDIS product line has been regarded as a reliable provider of high voltage
capacitors for circuit breakers and dividers for two decades,' said Lijiang Chi, Chief Engineer and Vice GM of XJ, a participant in the ZhangBei DC Grid Project.
This is to determine which loads will deliver savings from voltage
is defined as the work required to move a unit test charge in this field.
A typical oscillogram of voltage
and current pulses is shown on a nonlinear load in the form of a series connection of a gas bubble in water with a discharge in it and a layer of water under the bubble.
where [i.sup.*.sub.1d] and [i.sup.*.sub.1q] are the grid-side current command values in d-q coordinate system and [i.sub.1d] and [i.sub.1q] are the actual values; [u.sup.*.sub.1d] and [u.sup.*.sub.1q] are the grid-side voltage
command values in d-q coordinate system and [u.sub.1d] and [u.sub.1q] are the actual values; [U'.sub.dc], [U.sub.dc] are the reference voltage
and actual voltage
of DC bus, respectively; [K.sub.P1], [K.sub.I1], [K.sub.P2], and [K.sub.I2] are the parameters of PI controllers; L is the filter inductance of SST input stage.
On the other hand, the distribution static compensator (DSTATCOM) is a device used to mitigate voltage
sags and other PQ solutions such as power factor correction, voltage
stabilization, flicker suppression and harmonic control  .
The existing converter (Transformerless Cockcroft-Walton (CW) generator, or multiplier)    consists of one inductor Ls (boost inductor), four switches (Sm1, Sm2, Sc1, and Sc2) the rating of all switches are same as well as voltage
stress across each switch are same, and one n-stage CW voltage
multiplier The four switches are divided into two groups Sm1 (Sc1) and Sm2 (Sc2) which operate in two different frequencies of Sm1 and Sc1 are defined as fsm and fsc, respectively.
As the output of the precision rectifier can be the input of the next stage or to power another active element, larger PCE is desired so that next stage gives more DC output voltage
with feasible efficiency for its proper operation.
Increasing development of the solid-state power electronics switches leads the researchers to this area for voltage
In practice, the MMC-HVDC contains hundreds of submodules for reaching high voltage
; therefore, compared with the 21-level MMC in [9, 11], a 51-level converter is adopted in this paper to make the simulation closer to the engineering practice.
