Electronic load (E-load) is commonly used to test power supplies. In order to test computer power supplies, the E-load must possess an ideal controlled current source property which draws a desired load current even in the case of a very low terminal voltage of the source under test (SUT). It also needs to have superior dynamic performance to simulate high-slew-rate load transients. This paper proposes...

Fast transient response to step load change is very essential in a switch mode power supply. The transient response can be improved by means of feedback control method. In this paper a hardware implementation of SMPS power stage using half-bridge converter, employing positive voltage injection switching inductor (P-VISI) feedback control method for step-up load transient condition will be discussed...
Multi-resolution simulation offers rapid simulation of power electronics converters from very general to very detailed consideration. An approach for multi-rate simulation of switched linear system is considered here. A detailed full-order model of the converter is built that appropriately includes the system parasitic, switching nonlinearity, and switching event detection. Numerically-rigorous order-reduction...
