Core Capabilities

At HiT Power, we cover the complete journey from initial concept to successful implementation, ensuring every custom power electronics product meets your exact specifications and performs reliably in demanding applications. Our core capabilities include:

Design Expertise

Our design process is meticulous and comprehensive, leveraging decades of experience to create optimal power electronics solutions. We focus on:

  • System architecture: Developing robust and efficient system designs from the ground up, considering all operational parameters and environmental factors.
  • Loss analysis: Performing detailed analysis to minimise power losses, thereby maximising efficiency and reducing operational costs.
  • PCB layout: Expertly crafting Printed Circuit Board (PCB) layouts optimised to your exact specifications for performance and manufacturability.
  • Device and switching frequency selection: Carefully selecting the most suitable power semiconductor devices (Silicon (Si), Silicon Carbide (SiC), and Gallium Nitride (GaN)) and optimising switching frequencies for best balance between efficiency and size.

Topologies

We are proficient in a wide range of power converter topologies, allowing us to select or develop the most appropriate architecture for your specific needs:

  • Two-level and multilevel DC/AC Inverters: Designing and implementing advanced inverter solutions for grid-tied and standalone applications, offering enhanced waveform quality and reduced harmonic distortion.
  • Phase-shift full-bridge: Utilising this topology for high-power DC/DC conversion, known for its high efficiency and soft-switching capabilities.
  • Interleaved DC/DC converters: Implementing interleaved designs to reduce ripple currents, improve transient response, and distribute thermal loads, enhancing overall system reliability.
  • Bidirectional architectures: Developing bidirectional converters essential for energy storage systems, electric vehicles, and microgrids, enabling seamless power flow in both directions.

Packaging & Thermal Management

Effective packaging and thermal management are crucial for the longevity and reliability of power electronics. Our approach includes:

  • Discrete or module-based power stages: Designing power stages using either discrete components or integrated power modules, depending on the power level, density requirements, and cost considerations.
  • Forced-air or liquid cooling: Implementing advanced cooling solutions, including forced-air and liquid cooling systems, to maintain optimal operating temperatures and ensure consistent performance even under extreme conditions.

Control & Firmware

Our expertise extends to sophisticated control algorithms and firmware development, ensuring dynamic stability and optimal performance:

  • Model-based design and simulation: Utilising advanced simulation tools for time-domain and frequency-domain analysis to predict system behaviour and optimise control strategies before hardware implementation.
  • Real-time implementation: Developing and implementing high-performance control algorithms on digital signal processor (DSP) and field-programmable gate array (FPGA) platforms.

Communication and Interfaces

Seamless communication and integration are vital for modern power electronics systems. We ensure compatibility and interoperability through:

  • Standard communication protocols: Implementing industry-standard communication protocols such as CAN, Modbus TCP/RTU, and RS485/RS232 for reliable data exchange.
  • Ethernet connectivity: Providing Ethernet connectivity for high-speed data transfer and remote monitoring and control.
  • Integration with external systems: Ensuring seamless integration with Battery Management Systems (BMS), Energy Management Systems (EMS), and motor drive systems for holistic system operation.

Compliance & Reliability

We prioritise compliance with international standards and design for long-term reliability:

  • EMC and safety standards: Designing all converters to meet stringent Electromagnetic Compatibility (EMC) and safety standards, ensuring regulatory compliance and safe operation.
  • HALT/HASS-guided robustness: Employing Highly Accelerated Life Testing (HALT) and Highly Accelerated Stress Screening (HASS) methodologies to identify potential weaknesses and enhance the robustness and reliability of our designs.
