HBBPFC design and implementation project

DESCRIPTION

Power factor correctors or PFCs are developed as a solution to power consumption problems due to their high power factor, protect systems against voltage fluctuations and high currents.

The purpose of a PFC is that the input current follows the sinusoidal form of the line voltage, so that its unit power factor is obtained.

The HBBPFC is a converter designed to obtain 400VDC output, powered from the mains and obtaining a power factor PF = 1.

CIRCUIT FEATURES

HBBPFC is composed by one inductor, two capacitors, two transistors and the load, as the follow figure:

Figure 1: HBBPFC schematic circuit [1].

The current flows through the circuit creating two modes of operation through the alternating operation of each of the transistors.

PCBS DESING

This project has three printed circuits designed in Altium Designer, the first, the power stage or HBBPFC, the second, the signal conditioning stage with the control stage and, finally, the supply stage and its implementations were:

Figure 3: HBBPFC implementation [1].

POWER STAGE

The power stage is the plant or Half-Bridge Boost Power Factor Corrector and its PCB is:

SIGNAL CONDITIONING STAGE

SUPPLY STAGE

EXPERIMENTAL RESULTS

The following figures correspond to some of the results obtained in the implementation of the HBBPFC:

Figure 7: HBBPFC international project global testing [1].

Figure 8: HBBPFC international project Power Factor visualization [1].

Output voltage (vs) = 212.3 + 212.7 = 425V

PF = 1.

Power output = 83W.

FUTURE WORKS

Currently a new design of the power stage has been developed:

Figure 9: new desing of HBBPFC [1].

The development card used for the implementation of the control is obsolete, therefore, a new stage of signal conditioning (with supply stage was) designed using a PSoC 5LP (CY8CKIT-059 PSoC 5LP CY8C5888LTI_LP097).

Figure 10: new conditioning stage with supply included [1].

Another future work is to create a scientific paper (IEEE) with the achievements obtained in this project and to implement a new control strategy to improve results.

Resources are currently being searched to finance this project.
