Hi, I am an embedded systems engineer with 7+ years of experience in real-time motor control and power electronics firmware, having implemented SPWM/SVPWM on C2000 and STM32 platforms with switching frequencies up to 100 kHz and achieving <2% THD in inverter outputs under resistive and inductive loads. I have developed 30+ firmware-driven hardware systems, including full H-bridge and half-bridge converters, with optimized ISR latency below 2 µs and stable dead-time insertion for reliable MOSFET/IGBT operation. Approach: ✅ I will develop SPWM using timer peripherals with a sine lookup table and stable frequency control. ✅ I will configure complementary PWM with proper dead-time and basic protection handling. ✅ I will structure the code to be portable between C2000 and STM32 with clear abstraction. ✅ I will provide simple, well-documented code and verify output waveforms. Questions: ✅ I need to confirm the required output voltage and switching frequency. ✅ I need to know the gate driver and dead-time requirements. ✅ I need to confirm if only open-loop SPWM is needed or closed-loop control as well. Best, Yaroslav

Hi, this is a great project, especially because it’s teaching-focused. In this kind of setup, the code needs to be not only functional, but also clear, structured, and easy to explain, which is often where many implementations fall short. I can develop clean and well-documented SPWM control for your full H-bridge inverter, with a strong focus on readability, modular design, and portability between platforms. I’m comfortable working with both TI C2000 and STM32 families, and I would likely start with STM32G474 for flexibility, while keeping the architecture portable so you can migrate to F280039C later without major rewrites. Since this is for teaching, I’ll include clear comments and explanations around how SPWM works, how the timers are configured, and how the waveform is generated and updated. I can also include optional enhancements like adjustable frequency, modulation index control, and basic protection hooks if you plan to expand the system. You’ll receive clean source code, well organized and easy to follow, along with a short guide explaining how everything works and how to adapt it if you switch platforms later. If you have specific switching frequencies, modulation requirements, or hardware constraints, feel free to share them and I’ll tailor the implementation accordingly. Best regards, Jakub

@alluankit01

Hi, I can help with this. Since the goal is a **teaching-oriented full H-bridge inverter**, the important part is not just making SPWM run, but delivering **clean, well-documented firmware** that is easy to understand, test, and later port if you move between controllers. I would recommend building it first on **STM32G474** (or F280039C if you prefer), then structuring the code so the timer/PWM/control layer is kept modular for easier migration later. I can deliver: * SPWM firmware for the chosen platform * clear code comments and documentation * clean project structure for portability * practical notes for adapting the logic to the other MCU later What matters most here is making the firmware stable and educational, not overcomplicated. If you want, send me the inverter specs and preferred MCU first, and I’ll tell you the best implementation path right away. Best regards. Ankit.

@srinivasbakki81

You don’t just need “SPWM code.” You need something that is electrically safe, timing-correct, dead-time aware, and portable across MCU architectures—otherwise your H-bridge will happily destroy itself during a demo. So I’ll give you something you can actually work with, not hobby-grade. I’ll choose STM32G474 because Its advanced timers (TIM1/TIM8) are excellent for complementary PWM + dead-time, Easier dev ecosystem than C2000 for portability, Still close enough architecturally to port later to TMS320F280039C. Core Deliverables: SPWM firmware (STM32G474) Configurable Frequency, Modulation index, Dead-time safe switching,Full H-bridge drive logic Documentation: Timing diagrams, PWM waveform explanation and Porting guide to C2000

Hi there! You are building a teaching focused full H-bridge inverter with SPWM control and the real challenge is generating clean, portable modulation code that stays readable for students while still being hardware efficient. I recently developed SPWM firmware for an STM32 based motor drive where we achieved stable 20kHz switching with clean sine output and clearly structured, well commented control logic for learning use. I specialize in C firmware, timer based PWM systems, and embedded control design. I will implement SPWM using a timer driven PWM architecture with modular math so it stays portable between STM32G474 and TI C2000 with minimal changes. I will keep the code clean, fully documented, and structured for easy teaching and future extension. Check our work: https://www.freelancer.com/u/ayesha86664 Do you want pure open loop SPWM only, or should the design also leave hooks for future closed loop voltage regulation? I am ready to start — just say the word. Best Regards, Ayesha

@rogelitoc

Hello, In my opinion, the problem of this project is that a robust and portable SPWM implementation is required for dual platform compatibility. I will design the architecture to abstract platform-specific details while maintaining performance. The data flow will ensure efficient PWM generation with precise timing control, handling edge cases like varying input frequencies. I will leverage existing libraries for common functions and create a modular interface for the inverter control to facilitate easy migration between the Texas Instruments and STM32 platforms. The deliverable will be well-documented SPWM code, tested on both platforms, along with a concise user guide for implementation and migration. My background includes developing real-time embedded software for power electronics applications. I can start immediately. Regards.

@davidbsf0165

Hello I’m excited to submit my proposal for developing SPWM control code for your teaching-oriented full H-bridge inverter. This is a great project, and I understand the importance of keeping the implementation not only functional, but also clean, well-structured, and easy to learn from. I have solid experience in embedded systems and power electronics control, including PWM generation, inverter control, and microcontroller-based real-time applications. For this project, I would recommend using the TI F280039C (C2000) platform due to its dedicated high-resolution PWM modules and strong ecosystem for motor control and power conversion. That said, I will design the code in a portable and modular way so it can be migrated to STM32G474 with minimal effort. Sincerely

@salahuddin1973

Hello, I can help you develop a clean and well-structured SPWM control system for your full H-bridge inverter, designed specifically for a teaching-focused solar power setup. I’ve worked on embedded power electronics control before, so I understand the importance of both code clarity and stable PWM timing for inverter applications. I would recommend using the STM32G474 for this implementation due to its advanced timer peripherals (high-resolution PWM, complementary outputs, and dead-time control), but I can structure the code in a modular way so it remains portable to TI C2000 (F280039C) later. The SPWM will be implemented using timer-based sine lookup (or real-time generation if preferred), with proper dead-time insertion and safe switching logic for the H-bridge. The deliverable will include clean embedded C code, detailed comments, waveform explanation, and a simple guide so students can understand how modulation maps into switching behavior. Would you like the SPWM to support adjustable frequency and modulation index through UART or potentiometer input for teaching demonstrations? https://www.freelancer.pk/u/salahuddin1973 Best regards, Naufal
