Job Overview

We are seeking an experienced Power Engineer with expertise in designing, developing, and testing Photovoltaic (PV) Inverters for renewable energy applications. As a Power Engineer, you will be responsible for designing high-efficiency inverter systems, ensuring compliance with industry standards, and contributing to the overall optimization of PV system performance.

Responsibilities

Design and Development: Lead the development of power conversion systems, specifically PV inverters (DC-AC), focusing on efficiency, reliability, and cost-effectiveness.

Circuit Design: Design and simulate inverter circuits (e.g., power stages, filters, transformers) and associated components (IGBTs, MOSFETs, etc.) for PV applications.

System Optimization: Optimize inverter performance for efficiency, thermal management, and grid compatibility under various environmental and load conditions.

Control Algorithms: Develop and implement control algorithms (e.g., MPPT, grid synchronization, islanding detection) to maximize inverter performance.

Prototyping & Testing: Build and test prototypes to validate designs, troubleshoot issues, and iterate as needed to meet performance benchmarks.

Compliance & Standards: Ensure compliance with international standards (e.g., IEC, UL) and grid codes (e.g., IEEE 1547) for PV systems.

Collaboration: Work closely with cross-functional teams, including hardware engineers, firmware developers, and project managers, to ensure seamless integration of the inverter into larger PV systems.

Simulation & Modeling: Utilize simulation tools (e.g., MATLAB/Simulink) to model and analyze power electronics systems and components.

Documentation: Prepare detailed design documentation, including schematics, design calculations, test reports, and user manuals.

Qualifications

Education: Bachelor’s or Master’s degree in Electrical Engineering, Power Electronics, or a related field.

Experience:

• 5-7 years of experience in power electronics design, specifically with PV inverters or related renewable energy systems.
• Hands-on experience with designing high-power inverters.
• Experience in developing power electronic systems from concept through to production.

Technical Skills:

• Strong knowledge of power electronics, semiconductor devices, and circuit design.
• Proficiency in design tools such as Orcad, PSpice, or LTspice for circuit simulation.
• Familiarity with embedded systems and microcontroller programming for inverter control (e.g., DSP, FPGA).
• Experience with control theory and algorithms related to PV inverters (MPPT, grid-tied systems, etc.).
• Familiarity with international standards for PV inverters and grid interconnection.

Soft Skills:

• Strong analytical and problem-solving skills.
• Excellent communication and teamwork abilities.
• Ability to manage multiple projects and meet tight deadlines.

Preferred Qualifications:

• Experience with renewable energy systems (solar, battery storage, etc.).
• Familiarity with PV system design software (e.g., PVsyst).
• Knowledge of thermal management in power electronics.
• Familiarity with power system protection and energy storage technologies.
