The Advantages of UPMC technology in Power Conversion Applications
| The Advantages | ||||
|---|---|---|---|---|
| description | ||||
| Advanced algorithms | Advanced PID combined with non-linear control using look up tables event machines etc. allows optimal algorithms implementations. Providing different solutions for the different modes of operation of the controlled application (steady-state versus transient, low versus heavy load, etc.) | |||
| Fast control | Calculation and measurements are performed by custom logic for each controlled channel (not by CPU). | |||
| Complex Pulse Generator | State machine allows creation of multi state pulse sequences. The sequence/s can be modified on-the-fly. | |||
| Functionality per silicon area | The digital process tends to exist in smaller geometries offering lower cost solutions where there is a high degree of circuit function integration. | |||
| Easy clamp & reset | Inherent house-keeping capability - Protection thresholds are made flexible and precise by just updating the numerical parameters (like sensing temperature and changing thresholds or activating fans). | |||
| S/N | Signal to noise ratio of digital functions is better by definition and noise filtering can be more efficient using digital filters and digital masking. | |||
| Shortens design duration | The configuration capability with minimal code programming allows short time to market. | |||
| Component Count & reliability | The component reliability is dramatically improved, the digital functions are not subject to aging, tolerances. There is no need for component "select at test" and "select according to design spec". More functions can be integrated which decreases the component count and contributes to enhance the MTBF of the component and of the whole system. | |||
| Predictability / repeatability / Confidence | The digital design allows easier and more confident prediction of the product behavior. The component behavior will repeat itself precisely in production with absolute confidence. The production files will be simpler with less "special notes". | |||
| Ease of design Flexibility | Large degree of configurability of the control component including PID gains, programmable filters, sequences, and numerical parameters. All design and optimization is accomplished in front of a computer screen by means of a GUI designer tool through a communication bus. | |||
| On-the-fly configuration | Digital control allows on-the-fly modification of parameters in response to condition changes. | |||
| Easy to simulate | Digital is mathematical - the simulation does not have the complexity of the analog models and is not ambient dependent. | |||
| Field modification | There is a lot of elegance in hiding all the functions inside the control component and re-configuring and programming new functions instead of adding hardware patches to the application circuit. | |||
