IMPROVED PULSE STEP MODULATOR

摘要

A pulse step modulator including a plurality of series connected unit step modules, each with a DC voltage source and an associated actuatable switch for, turning on the associated to provide a unit step voltage. An output circuit connected to the series connected modules for providing an output voltage to a load, the magnitude of the output voltage being equal to the sum of all the voltage sources of the modules that are turned on. A plurality of module turn on signals are provided, each for turning on a switch on one of the modules for the time duration of the turn on signal after which the switch is turned off. Each unit step module includes a transformer means exhibiting an associated unwanted capacitance becomes charged when the associated switch is turned on. Each unit step module has capacitance discharge means.
