EMC, Volume & Cost optimized Bidirectional Inverter
Our patented inverter technology enables the development of
- High-efficiency bidirectional inverters
- That are EMC-optimized,
- Compact (High power density),
- And cost-efficient.
At the core of this innovation is a new inverter topology that fully leverages the advantages of Wide Bandgap (WBG) semiconductors (SiC / GaN).
It enables
- Higher switching frequencies
- Combined with zero-voltage
- And zero-current switching,
Unlocking performance levels that conventional topologies cannot achieve.
SiC / GaN based technology
Ultra-low EM emission (best in class)
Summary of the Key Advantages
1. Significantly Reduced High-Frequency Harmonics
The topology minimizes harmonic distortion at high frequencies, improving EMC behaviour and reducing filtering effort.
2. Nearly Perfect Sinusoidal Voltage & Current Generation
The inverter can generate highly controllable, low-distortion sinusoidal waveforms; ideal for demanding drive and motion applications.
3. Enhanced Servo-Drive Performance
Cleaner waveforms and reduced harmonics directly improve the dynamic behaviour and efficiency of servo-drive systems.
4. Full Utilization of WBG Benefits
The topology enables:
- Higher switching frequencies
- Zero-voltage and zero-current switching
- Lower switching losses
- More compact and efficient designs
5. Strong Reduction of PWM-Induced Machine Losses
Lower harmonic content and optimized switching dramatically reduce machine losses caused by the inverter; increasing overall drive-system efficiency.
6. Significant Cost Reduction (e.g., Cable Shielding)
Improved EMC behavior reduces or eliminates the need for expensive shielding and filtering measures.
Minimizing electromagnetic interference reduces the risk of electronic failures and lowers approval and testing efforts.
Did you know that a converter generating a pure sine wave AC output (non-PWM) can dramatically reduce electromagnetic emissions?
