Huawei's Ohm Research Center (Nuremberg) is responsible for Advanced Technology Research, Architecture Evolution Design and Strategic Technology Planning.

The Power Conversion Technology Laboratory within the Huawei Ohm Research Center (Nuremberg) is responsible for Advanced Digital Power Technology Research, Architecture Evolution Design and Strategic Technology Planning, and plays an important role in the Huawei Digital Power business in the design and development of power converters and control systems for applications such as PV Solar & Battery Energy Storage Field, Data Centers, Electric Vehicle, and Embedded Power Supply.

Join us as a

Own the control architecture for medium-voltage converter products, including control hierarchy, closed-loop design, modulation, sequencing, protection coordination and fault management.
Develop and validate current, voltage and power control, DC-link or capacitor balancing, multilevel modulation and synchronization algorithms.

Assess the impact of converter topology, power semiconductors, magnetics, sensing, gate drives and protection on control performance.
Lead the real-time implementation of control algorithms on DSP, FPGA, MCU or SoC platforms.
Define functional partitioning, real-time interfaces, synchronization and fault-response paths across controllers.
Drive validation from modelling, SIL/PIL and HIL through power test benches, prototypes and field commissioning.
Resolve system-level issues involving oscillations, weak-grid interactions, power-cell imbalance, harmonics, nuisance trips and cell bypass.

Establish reusable control modules, design guidelines and commissioning methods.

Deep understanding of power converter dynamics, digital control, closed-loop stability, sampling and delay effects.
Strong knowledge of current, voltage and power control, multilevel PWM, synchronization and power-cell balancing.
Good understanding of medium-voltage multilevel topologies, power semiconductors, magnetics, DC links, sensing, gate drives and protection.
Proficiency in Embedded C/C++ and experience with DSP, MCU, FPGA or SoC control platforms.

Ability to handle algorithm discretization, fixed- or floating-point implementation, execution timing and computational-load optimization.

Practical capability in power test-bench and prototype commissioning, using waveforms, logs and measurement data for system analysis.
Ability to drive technical decisions across control, hardware, software and system teams.
At least 10 years of industrial experience in power converter control.
Hands-on development experience with medium-voltage or high-power converter products.
Demonstrated ownership of at least one relevant product, covering control concept, embedded implementation, prototype or system validation, and progression into field operation or series production.
Experience with medium-voltage drives, STATCOM, HVDC, utility-scale energy storage PCS, wind converters or comparable products is preferred.
Experience with CHB, MMC, NPC/ANPC or other medium-voltage multilevel topologies is preferred.

Practical experience with HIL testing, power test benches or field commissioning.
