A digital-to-analog conversion method includes outputting one priority bit of a digital signal to a digital output port to produce a respective output signal. An output time for the output signal is obtained by multiplying a unit of time by a weight of coding representing the significance of the bit, to define a period of time of maintaining the signal level at the output port before shifting to a next bit, and repeating the aforesaid steps for the successive bits. The output signal produced can be used to directly drive a power switching means for linear control of a power element, or integrated and filtered to provide a level analog output.
