Gradient-reference-current (GRC) control strategy is proposed to achieve better dynamic response for tri-state buck converter over a wide load variety without additional hardware. By designing the logical current comparing element without load current detection, the conduction mode of tri-state buck converter under GRC control could be switched between discontinuous conduction mode (DCM) and pseudo...
State-of-the-art LC filter design of buck DC-DC converter is based on the specifications of voltage and current ripples and constrains in power density and cost. Since lifetime is an important performance factor in reliability critical applications, this digest proposes a method to optimize the design of the LC filters from a reliability perspective, among other considerations. It investigates the...
With the wide application of power electronic equipment, more and more attention has been paid to the power quality of power supply system. For three-phase/switch VIENNA rectifier with a high power factor, one cycle control is a reliable and simple non-linear large signal control method. For the design of VIENNA rectifier, the balance of dc-link neutral-point voltage is important, especially when...
