摘要： An audio system, an audio apparatus, and a method for performing audio signal output processing are provided that prevent the occurrence of sound interruption of high-priority voice signal output, such as voice guidance for navigation. The audio system includes the audio apparatus communicatively connected to an electronic device for producing an audio signal and to an electronic device for producing a high-priority voice signal (voice guidance signal). When the voice guidance signal is received with the audio signal being received, the audio apparatus starts to perform a mixing operation of the voice guidance signal. If a request for switching a sample rate of the audio signal is made during the mixing operation, the audio apparatus suspends a sample-rate switching operation until the mixing operation is completed.

摘要： The power converter of the invention relates to a small-sized highly efficient power converter for generating an a.c. voltage output of multiple levels with less harmonic content. In the power converter, a d.c. voltage source is separated into plural sections by series connected voltage dividing capacitors and multiple levels of a.c. output voltage are obtained from the divided d.c. voltage by on-off control of switching devices. The power converter has plural sets of the voltage dividing capacitors disposed separately adjacent to each switching devices, and series connection point of each set of the voltage dividing capacitors are connected to division points of the corresponding switching devices of each phase. The voltage dividing capacitors are connected with each other at their series connection points. Thereby, the arrangement makes wiring length short and equal between the switching devices and the voltage dividing capacitors for each phase and reduce a loss in the snubber circuit, resulting in an a.c. voltage output with less harmonic content.
