Multi-dimensional pulse-width modulating method and multi-dimensional pulse-width modulating signal generator

Abstract

The invention relates to a multi-dimensional pulse-width modulating method and a multi-dimensional pulse-width modulating signal generator. The multi-dimensional pulse-width modulating method can be used for sampling inputted signals to generate the pulse-width modulating signal including at least one pulse modulation. The energy contained in the pulse-width modulating signal is expressed by a data bit combination which uses at least three of the control bits including a pulse-width modulating control bit, a current control bit, a voltage control bit and a repetitive-rate control bit for adjusting the energy contained in the pulse-width modulating signal. The multi-dimensional pulse-width modulating signal generator comprises a pulse encoding modulator, a multi-dimensional pulse-width modulating controller and a multi-dimensional pulse-width modulating driver. The multi-dimensional pulse-width modulating method can improve the resolution of the pulse-width modulating signal, and the multi-dimensional pulse-width modulating signal generator can overcome the defect of the insufficient resolution of the pulse-width modulating signal, thus the invention is practical.

Description

technical field [0001] The present invention relates to a pulse width modulation method and a pulse width modulation signal generating device thereof, in particular to a multi-dimensional pulse width modulation method and a multi-dimensional pulse width modulation signal generating device considering more than three variables ( Multi-Dimension Pulse Width Modulation Method and Multi-Dimension Pulse Width Modulation Signal Generating Apparatus). Background technique [0002] Pulse Width Modulation (Pulse Width Modulation, PWM) uses different duty cycles to represent various signals (signals are signals, which are referred to as signals in this article). see figure 1 Shown is a waveform diagram of a pulse width modulation (PWM) signal used in the prior art. In this technique, the waveform of the pulse width modulation (PWM) signal is composed of square waves of different widths, with wider square waves representing higher energy and narrower square waves representing less po...
