This paper presents the development of a control scheme for a multilevel diode-clamped converter connected in a series–parallel fashion to the electrical system such that it can compensate for deviations in utility voltage (sag, surge, and unbalance) and act as a harmonic and/or reactive current source for a load. New carrier-based multilevel pulsewidth modulation techniques are identified to m...

Abstract A set of portable constant pulse current sources with STM32 as the control core is developed, which mainly involves SCM module, operational amplifier circuit output power key and display module. Based on traditional constant-current source design, real-time system constructed by software programming optimization, has characteristics strong stability. By connecting field effect tube in ...
