Space-vector-modulated three-level inverters with a single Z-source network [PDF]

, 2012
The Z-source inverter is a relatively recent converter topology that exhibits both voltage-buck and voltage-boost capability. The Z-source concept can be applied to all dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversion whether two-level or ...

Parallel diode‐clamped linear converter for withstand test and partial discharge measurement of electric equipment

High Voltage, 2023
High‐voltage withstand tests are essential for electric equipment like power transformers, electric cable lines, gas insulated switchgears etc. The partial discharge (PD) measurement for such equipment under applied high voltage is also required at the ...

Battery charger with a capacitor-diode clamped LLC resonant converter [PDF]

, 2016
The paper proposes a novel battery charger through use of two serially-connected LLC resonant converters. The first stage utilises a capacitor-diode clamped LLC resonant converter which allows operation in both constant voltage (CV) and constant ...

Three-Phase Diode-Clamped Four-Level PWM Inverter With Offset Voltage Injection

IEEE Access
In this paper, a three-phase diode-clamped four-level PWM inverter with offset voltage injection is proposed. The proposed inverter is based on multi-neighboring reference vector (discontinuous) pulse-width modulation (MNRV (D)PWM), where multiple ...
