We begin every project with a rigorous engineering process to identify and optimize the most suitable inverter topology for the intended application. Our expertise covers:

• DC‑link design and semiconductor device selection
• Switching strategy development
• Passive component sizing based on steady‑state, transient, and fault conditions
• Loss modelling, thermal analysis, and harmonic compliance
• Full alignment with international standards and grid codes

These optimized inverter architectures are deployed across FACTS devices, Battery Energy Storage Systems (BESS), and advanced grid‑forming converter applications.

KHAS Consulting develops robust, multi‑layer control frameworks that ensure stable and reliable grid‑connected operation under all conditions. Our capabilities include:

• Inner current control and outer voltage/power regulation
• DC‑link stabilization and grid synchronization
• Grid‑following and grid‑forming control strategies
• PLLs, droop control, virtual synchronous machines, and inertia emulation

We apply small‑signal modelling, impedance‑based analysis, and systematic controller tuning to guarantee stability, fast dynamic response, and resilience in weak or low‑inertia grids.

Our team builds detailed, physics‑based models that accurately represent converter–grid interactions. These models incorporate:

• Switching behaviour and LCL filter dynamics
• Grid impedance variability and nonlinear loads
• Disturbance and fault scenarios

Through time‑domain and frequency‑domain simulations, we validate harmonic performance, voltage/frequency regulation, fault‑ride‑through capability, and overall system robustness before moving to hardware testing

We specialise in the development of soft‑switching techniques that dramatically improve inverter efficiency and electromagnetic performance. Our R&D focuses on:

• Zero Voltage Switching (ZVS) and Zero Current Switching (ZCS)
• Auxiliary resonant networks and advanced modulation strategies
• Passive and active snubber structures
• Device stress reduction and EMI mitigation

These solutions are engineered to maintain grid compliance, current quality, and control stability — even under weak grid conditions or dynamic load changes.

Soft‑switching technologies developed by KHAS Consulting are ideally suited for high‑power applications including FACTS devices, BESS interfaces, and grid‑forming converters

To bridge the gap between simulation and deployment, KHAS Consulting uses real‑time HIL platforms to validate control algorithms under realistic grid conditions. This enables:

• Closed‑loop testing without physical system risk
• Verification of real‑time computational performance
• Assessment of protection coordination and disturbance response

HIL validation significantly reduces development risk and accelerates the path to field‑ready solutions

Our research directly supports the global shift toward renewable energy, large‑scale storage, electric mobility, and digitally controlled industrial loads. By integrating:

• Advanced control strategies
• High‑fidelity system modelling
• Real‑time HIL validation
• High‑efficiency soft‑switching converter technologies

KHAS Consulting delivers resilient, intelligent, and future‑proof power electronic solutions.

We help utilities and energy stakeholders across the UK, Europe, and international markets modernize their grids and accelerate the transition to a cleaner, more flexible energy ecosystem.
