Single-Stage Single-Switch Input-Current-Shaping Technique with Fast-Output-Voltage Regulation
A new single-stage single-switch input-currentshaping (S4ICS) technique, which combines the boost-like input-current shaper with a continuous-conduction-mode (CCM) dc/dc output stage, is described. In this technique, the boost inductor can operate in both the discontinuous conduction mode (DCM) and CCM. Due to the ability to keep a relatively low voltage (<450 Vdc) on the energy-storage capacit...
متن کاملSingle-Stage, Single-Switch Input-Current-Shaping Technique with Reduced Switching Loss
In this paper, a new single-stage, single-switch input-current-shaping (SICS) technique which features substantially reduced turn-on switching loss of the switch in a SICS flyback topology is described. In the proposed technique, the turn-on switching loss due to the discharging of the output capacitance of the switch is reduced by turning on the switch when its voltage is minimum. To achieve t...
متن کاملSingle-Stage Input-Current-Shaping Technique with Voltage-Doubler-Rectifier Front End
In this paper, a new single-stage input-currentshaping (ICS) technique that integrates the voltage-doublerrectifier front end with a dc/dc output stage is introduced. Due to the voltage-doubler-rectifier front end, the reduction of linecurrent harmonics can be achieved with a higher conversion efficiency compared to the corresponding single-stage ICS circuit with the conventional wide-range ful...
متن کاملA Single Phase Single Stage AC/DC Converter with High Input Power Factor and Tight Output Voltage Regulation
A single stage single switch AC/DC converter is an integration of input current shaper and a DC/DC cell with a shared controller and one active switch. The converter is applicable for digital input power supply with high input power factor and tight output voltage regulation. The focus of the topology is to reduce the DC bus voltage at light load without compromising with input power factor and...
متن کاملA Novel ±0.5V Ultra High Current Drive and Output Voltage Headroom Current Output Stage with Very High Output Impedance
A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...
