Plug-in Hybrid Electric Vehicles (PHEVs) and Electric Vehicles (EVs) are an emerging trend in the field of automotive engineering. At the same time, consumer’s interest is growing rapidly. With the fluctuations in the universal supply, it is mandatory to maintain unity power factor. Power factor correction is essential to meet the efficiency and regulatory standards for the AC supply mains. Four types of PFC converters have been investigated and the results have been discussed. Out of which bridgeless interleaved PFC converter is suited for power levels up to 5kW.
In this paper, a phase shifted semi-bridgeless boost power factor corrected converter is proposed for plug in hybrid electric vehicle battery chargers. The converter features high efficiency at light loads and low lines, which is critical to minimize the charger size, charging time and the amount and cost of electricity drawn from the utility; the component count, which reduces the charger cost; and reduced EMI. The converter is ideally suited for automotive level I residential charging applications.
Single-Phase PFC Converter for Plug-in Hybrid Electric Vehicle Battery Chargers
International Journal of Power Electronics and Drive Systems (IJPEDS), 2012
In this paper, a front end ac-dc power factor correction topology is proposed for plug-in hybrid electric vehicle (PHEV) battery charging. The topology can achieve improved power quality, in terms of power factor correction, reduced total harmonic distortion at input ac mains, and precisely regulated dc output. Within this context, this paper introduces a boost converter topology for implementing digital power factor correction based on low cost digital signal controller that operates the converter in continuous conduction mode, thereby significantly reducing input current harmonics. The theoretical analysis of the proposed converter is then developed, while an experimental digital control system is used to implement the new control strategy. A detailed converter operation, analysis and control strategy are presented along with simulation and experimental results for universal ac input voltage (100-240V) to 380V dc output at up to 3.0 kW load and a power factor greater than 0.98. Experimental results show the advantages and flexibilities of the new control method for plug-in hybrid electric vehicle (PHEV) battery charging application.
Electrical car generation is a new subject for the last decade and li-ion battery is the heart of its energy source. So, there are many works about single phase power factor correction (PFC) boost converters in the literature to charge li-ion batteries . As a comparison, conventional and interleaved PFC boost converters are simulated at the same conditions for the performance evaluation. Simulations are operated at 3 kW output power and 400 V output voltage with 100 kHz switching frequency and they are compared by power factor (PF), total current harmonic distortion (THDi) and total efficiency values. According to the simulation results, conventional boost converter has 97.8 % efficiency and 4.88 % THDi values, however interleaved boost converter has greater 98 % efficiency and 1.93 % THDi values. Although these converters have higher than 0.99 power factor, interleaved PFC boost topology has better performance for li-ion battery charging.

As a key component of a plug-in hybrid electric vehicle (PHEV) charger system, the front-end ac-dc converter must achieve high efficiency and power density. This paper presents a topology survey evaluating topologies for use in front end ac-dc converters for PHEV battery chargers. The topology survey is focused on several boost power factor corrected converters, which offer high efficiency, high power factor, high density and low cost. Experimental results are presented and interpreted for five prototype converters, converting universal ac input voltage to 400 V dc. The results demonstrate that the phase shifted semi-bridgeless PFC boost converter is ideally suited for automotive level I residential charging applications in North America, where the typical supply is limited to 120 V and 1.44 kVA. For automotive level II residential charging applications in North America and Europe the bridgeless interleaved PFC boost converter is an ideal topology candidate for typical supplies of 120 V and 240 V, with power levels of 3.3 kW, 5 kW and 6.6 kW.

A plug-in hybrid electric vehicles (PHEV) charger adapter consists of an AC/DC power factor correction (PFC) circuit accompanied by a full-bridge isolated DC/DC converter. This paper introduces an efficient two-stage charger topology with an improved PFC rectifier as front-end and a high-frequency zero voltage switching (ZVS). Current switching (ZCS) DC/DC converter is the second part. The front-end converter is chosen as bridgeless interleaved (BLIL) boost converter, as it provides the advantages like lessened input current ripple, capacitor voltage ripple, and electromagnetic interference. Resettable integrator (RI) control technique is employed for PFC and DC voltage regulation. The controller achieves nonlinear switching converter control and makes it more resilient with the faster transient response and input noise rejection. The second stage incorporates a resonant circuit, which helps in achieving ZVS/ZCS for inverter switches and rectifier diodes. PI controller with phase sh...
