Method for avoiding or reducing noise interference in a converter circuit with multiple simultaneously operated outputs |
摘要 |
<p>The outputs of the circuit are each connected to a load, especially an induction coil, and are operated with first and second switching frequencies respectively. The method involves operating the circuit so that the frequency of acoustic noise is lower than a first threshold and/or greater than a second threshold. The power of at least one output can be regulated by varying the relative on-time or switching frequency.</p> |
