PULSE-WIDTH MODULAR CIRCUIT AND METHOD FOR CONTROLLING A PULSE-WIDTH MODULAR CIRCUIT

摘要

The invention relates to a pulse-width modulator circuit for the production of a reference signal exhibiting a desired pulse duty factor, comprising an adjustment unit comprising at least one memory register and a counter. The memory register is configured in order to store values which correspond at least approximately to the desired pulse duty factor in order to produce the reference signal. The counter adjusts a cycle number Y indicating how often a stored first value X is read from the memory register during work cycle A. The value stored in the memory register can be modified during the work cycle.
