text: Modular solid-state transformers (SSTs) are a promising technology in converting
power from a 10kV three-phase medium voltage to a lower DC-voltage in the range
of 100…400V to provide pure DC power to applications such as electrolyzers for
hydrogen generation, data centers with a DC power distribution and DC micro grids.
Modular SSTs which can be interpreted as modular multilevel converters with an
isolated DC-DC output stage per module, are designed with redundant modules to
increase reliability. Usually, each of the three arms operates independently,
and therefore, only a fixed number of faulty modules can be compensated in each
arm, even if all modules are operational in the remaining two arms. With the proposed
zero-sequence voltage injection, up to 100% more faulty modules can be compensated
in an arm by employing the same hardware. In addition, module power imbalances
are nearly eliminated by utilizing a fundamental frequency zero-sequence voltage.
A dominant 3rd harmonic zero-sequence voltage injection in combination with the
5th, 7th and several higher order harmonics with adaptive (small) amplitudes minimize
the required arm voltages at steady-state. For nominal operation or symmetrical
faults, the proposed technique is equivalent to the well known Min-Max voltage
injection, which already reduces the peak arm voltage by 13.4% compared to a constant
star point potential. A statistical analysis proves, that the expected number
of tolerable faulty modules of the 1MW SST increases by 12% without the need for
additional hardware.

text: Phase-shift modulated full bridge converters suffer from thermal imbalances
of the inverter switches. The lagging leg switches are subject to larger commutation
currents compared to those of the leading leg as the transformer current reduces
in the freewheeling interval. Furthermore, after this interval, the energy in
the series inductance may not be large enough to achieve zero-voltage switching
(ZVS) for the leading leg. Both effects result in thermal imbalances. This paper
analyzes the alternating-asymmetrical phase-shift modulation to achieve balanced
conduction and switching losses for all four switches while showing that this
modulation is easily implemented on standard DSPs. The modulation has been implemented
to LLC converters where experimental measurement results proved its effectiveness
for LLC converters by reducing the temperature deviation from 6.3 K to only 0.2
K such that the peak temperature is reduced from 95 °C to 92 °C. The paper also
proves that the modulation can be utilized to improve the efficiency of LLC converters
operated at very low gains while simultaneously reducing the junction temperature
of all four switches compared to the conventional complementary modulation. Finally,
EMI implications are analyzed, which show that the modulation may be beneficial
for reducing the common-mode emissions around the operating frequency.

text: LLC resonant converters are typically unsuitable to be applied for wide voltage-transfer
ratio applications. With a full-bridge inverter, however, they can be operated
in a variety of different modulations. Most notably, by permanently turning on
one MOSFET and turning off the other MOSFET of the same bridge leg, the LLC can
be operated in half-bridge configuration reducing the gain by a factor of two.
The resonant capacitor is hereby charged to an average voltage of half the input
voltage. In this modulation, however, the switch that is permanently turned on
is stressed by the complete resonant current while exhibiting no switching losses.
This paper proves that the frequency-doubler modulation can better balance the
losses among all MOSFETs and should be the preferred mode of operation favored
over the conventional half-bridge modulation. This paper analyzes the beneficial
loss distribution, proposes an on-the-fly morphing modulation and discusses potential
operating strategies to further reduce the junction temperature. Furthermore,
it is shown that this modulation can also be altered to achieve the asymmetrical
LLC operation. Experimental measurement results show that the modulation results
in a substantial decrease of the maximum MOSFET temperature and shows that the
converter can be smoothly transitioned during operation from full-bridge modulation
to the frequency-doubler half-bridge operation and back.

- lang: eng
text: In this paper, a full-bridge modular multilevel converter (MMC) and two half-bridge-based
MMCs are evaluated for high-current low-voltage e.g. 100 - 400V DC-applications
such as electrolysis, arc welding or datacenters with DC-power distribution. Usually,
modular multilevel converters are used in high-voltage DC-applications (HVDC)
in the multiple kV-range, but to meet the needs of a high-current demand at low
output voltage levels, the modular converter concept requires adaptations. In
the proposed concept, the MMC is used to step-down the three-phase medium-voltage
of 10kV, and provide up to 1 MW to the load. Therefore, each module is extended
by an LLC resonant converter to adapt to the specific electrolyzers DC-voltage
range of 142 - 220V and to provide galvanic isolation. The six-arm MMC converter
with half-bridge modules can be simplified and optimized by removing three arms,
and thus halving the number of modules. In addition, the module voltage ripple
and capacitor losses are decreased by 22% and 30% respectively. By rearranging
the components of the half-bridge MMC to build a MMC consisting of grid-side full-bridge
modules, the voltage ripple is further reduced by 78% and capacitor losses by
64%, while ensuring identical costs and volume for all MMCs. Finally, the LLC
resonant converter is designed for the most efficient full-bridge MMC. The LLC
can not operate at resonance with a fixed nominal module voltage of 770V because
the output voltage is varying between 142 - 220V. By decreasing the module voltage
down to 600V, additional points of operation can be operated in resonance, and
the remaining are closer to resonance. The option to decrease the module voltage
down to 600V, increases the number of required modules per arm from 12 to 15,
which requires to balance the losses of the LLCs and the grid-side stages.
