At SOLWIT Engineering and Consultancy, we turn complex control mathematics into rugged, high-reliability embedded realities. Our multi-disciplinary engineering team specializes in the complete hardware and firmware lifecycle for both low-power micro-drives and megawatt-class high-power inverter controllers. We bridge the gap between abstract control theory and physical execution, delivering optimized PCBs and deterministic, real-time firmware designed to withstand harsh electrical and thermal environments.
Our Embedded Ecosystem
1. Hardware & Power Electronics Design
We design and prototype robust, high-density PCBs tailored for extreme power dynamics and strict electromagnetic compatibility (EMC).
- High-Power Inverter Hardware: Expertise in designing gate driver stages, busbar layouts, and advanced thermal management for SiC (Silicon Carbide) wide-bandgap semiconductors.
- Low-Power Integrated Drives: High-density, multi-layer mixed-signal PCB designs that integrate the microcontroller, gate driver, and MOSFETs into ultra-compact form factors.
- Signal Integrity & Protection: Implementation of isolation techniques (galvanic/optical), high-speed current/voltage sensing, and ultra-fast hardware-level overcurrent, overvoltage, and thermal protection loops.
2. Real-Time Control Firmware
Motor control demands microsecond-level determinism. Our firmware is architected for zero-latency execution of complex mathematical vectors.
- Advanced Architecture: Bare-metal development and RTOS optimized for leading motor control chipsets (TI C2000 Delfino/Piccolo, STMicroelectronics STM32G4/F4, Infineon Aurix).
- Deterministic Execution: Designing time-critical ISRs for FOC, Space Vector PWM generation, and high-speed sensorless observers.
- Industrial Communication: Seamless integration of CANopen, Modbus, EtherCAT, and automotive-grade LIN/CAN-FD.
Embedded Development Workflow
- Model-Based Design (MBD): Developing and simulating control loops before auto-generating production-ready C-code.
- Hardware-in-the-Loop (HIL) Testing: Validating firmware against real-time digital twins of PMSM and Axial Flux motors before flashing onto physical prototype boards.
- Rigorous Laboratory Validation: In-house testing using high-bandwidth oscilloscopes, programmable DC loads, and dynamometers to ensure stability under transient load conditions.
