Pulse width modulator, particularly for controlling motor or switch mode power supply, has N-Bit counter with selected increment, which is provided for producing temporary sequence of readings per metering cycle from counter value

摘要

The pulse width modulator (10) has an N-Bit counter (12) with a selected increment, which is provided for producing a temporary sequence of readings per metering cycle from counter value, which encompasses exactly once all 2N values between a initial value and a maximum value. The individual readings are spaced around the increment from the predecessor or subsequent value. A comparator (14) is provided for comparing each reading of the counter with a reference value. An independent claim is also included for a method for producing pulse width control signal.
