System for controlling an inverter through pulse width modulation |
摘要 |
A system provides parallel sequences of control signals, each control signal having a determined duration (T), constant within a sequence, and a predetermined duty cycle, specific to the control signal. A microcontroller (20) includes a central processing unit (21) and a non-volatile memory (23) arranged in blocks (Bij) of lines and columns. Each line corresponds to a word containing at least as many bits as parallel sequences. A Direct Memory Access (DMA) controller (24) and an associated counter (25) sequentially address each word of a block at a fixed frequency and supply bits of this word in parallel to produce the parallel control signals.
