Senior Engineer – Medium Voltage Power Converter Control (m/f/d)

Your mission

• 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.

Your areas of expertise

• 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.
