This paper emphasize on the investigation of small-signal behavior of a Coupled Inductor Bidirectional DC-DC (CI-BDC) converter being controlled by a Voltage Mode Control (VMC) technique. The small-signal model including converter parasitics is derived using the SS averaging technique. This linearised converter modeling makes the design of closed loop controller much easier. The closed loop model...
This paper introduce a new isolated bridgeless AC to DC converter with power factor correction capability. This power factor correction (PFC) circuit is capable to perform the AC to DC conversion without the diode bridge rectifier and able to obtain low output voltage which is more suitable to most applications. The detail small signal and steady state analysis of the converter operated in discontinuous...
The SIDO converter is appealing in low-power applications requiring two independent supply voltages. The use of a single inductor significantly reduces the cost and size of the converter, however the complexity of the controller is greatly increased due to the inherent coupling of the two output voltages in continuous conduction mode. The accuracy of the traditional averaging technique is examined...
In comparison with other types of synchronous generators, permanent magnet synchronous generator (PMSG) has the advantages of higher efficiency, simplicity in construction and reliability in operation. This paper presents a multi-stage 3-phase AC/DC PWM converter. The proposed converter is designed to extract the maximum power from the PMSG side and avoid speed sensing. Furthermore, the controller...
Distributed Power System (DPS) have many loads with varied functions. In particular, there may be large pulsed loads with short duty ratios which can affect the normal operation of other loads. In this paper, a converter with spilt capacitors and an adaptive controller is proposed as a Voltage Bus Conditioner (VBC) to mitigate the voltage transients on the bus. The proposed converter allows the smaller...
The clean energy sources such as solar cells, fuel cells and photovoltaic are attractive in the present time as fossil energy cannot be renewed and the price is soaring in recent years. A system converting solar energy to electricity and connecting to the utility network is proposed in this paper. DC-DC converter becomes necessary in this system. In order to obtain a stable output DC voltage, an improved...
There are many analyses on the closed-loop performance for COT buck converters. But all of them assume the absence of the multiple pulsing effect, which will increase the output voltage and inductor current swing significantly, and a poor steady state performance is as a result. This paper presents a time domain analysis for COT buck converters to show the relationship between the multiple pulsing...
