Impedyme FPGA Scope
系统 Impedyme FPGA Scope is a built-in, high-speed signal visualization and diagnostics tool engineered specifically for Impedyme’s CHP Series real-time simulation platforms. Deeply integrated into Impedyme’s FPGA-centric real-time control and signal-processing architecture, the FPGA Scope enables engineers to monitor, trigger, and analyze critical electrical and control signals with sub-microsecond resolution — all without external oscilloscopes or DAQ hardware.
This tight FPGA integration makes the Impedyme FPGA Scope a core differentiator for advanced 电力硬件在环（PHIL）, Controller HIL, and grid-compliance validation workflows.
Purpose and Use Case
In modern HIL and PHIL testing environments, engineers face increasing system complexity, higher switching frequencies, and stricter compliance requirements. Traditional software-based scopes or external instruments often fail to capture true real-time behavior.The Impedyme FPGA Scope is purpose-built to address these challenges by allowing engineers to:
1
Observe internal system states (Id/Iq, Vabc, Vdq, controller states, integrator outputs)
2
Validate timing-critical signals (PWM edges, PLL lock behavior, fault logic response)
3
Troubleshoot control algorithm performance in real time
4
Analyze transient events, fault ride-through, and grid disturbances
Engineering Challenges Solved by Impedyme FPGA Scope
Modern power electronics and real-time simulation environments introduce engineering challenges that traditional measurement and debugging tools struggle to address. The Impedyme FPGA Scope is specifically designed to solve these problems by providing deterministic, FPGA-level visibility into fast, timing-critical systems. Below are the most common engineering challenges and how Impedyme’s FPGA Scope overcomes them.
1. Missed Transient Events in High-Speed Systems
Challenge:
Fast transients like voltage dips, switching spikes, or fault triggers can occur within microseconds and are often missed by external tools.
Solution:
-
- Captures signals directly inside the FPGA execution path
- Sub-microsecond time resolution
- Pre-trigger and post-trigger event capture
2. Control Loop Instability and Tuning Issues
Challenge:
Control loops may become unstable due to timing mismatches, saturation, or integrator windup.
Solution:
- Access to internal controller states
- Real-time comparison of reference and feedback signals
- Live tuning with instant waveform validation
3. PHIL Loop Oscillations and Stability Problems
Challenge:
Power Hardware-in-the-Loop setups can experience oscillations caused by latency or impedance mismatch.
Solution:
- Deterministic capture synchronized with PHIL timing
- Simultaneous monitoring of voltage, current, and impedance signals
- Trigger-based capture during instability events
4. PWM Jitter and Switching Debugging
Challenge:
High-frequency PWM signals require precise timing analysis to detect jitter or duty-cycle distortion.
Solution:
- FPGA-level visibility of PWM timing
- High-resolution switching-cycle analysis
- Accurate transition timing measurements
5. Synchronization Across Control and Simulation Domains
Challenge:
Timing misalignment between control logic and simulation models can affect testing accuracy.
Solution:
- Signals captured within the same real-time clock domain
- Deterministic synchronization with simulation steps
- Time-aligned waveform capture
6. Limited Visibility Into Internal FPGA Signals
Challenge:
Traditional tools often cannot access internal FPGA signals during real-time operation.
Solution:
- Direct monitoring of internal FPGA variables
- Real-time signal inspection without external probes
- Improved debugging of embedded control logic
