INSTRUCTIONS::: TECHNICAL FIELD OF THE INVENTION The present invention relates to a full-bridge electronic ballast (electric factor correction 'PFC) circuit with a resonant tank for a read current mode charging pump power factor correction (PFC) circuit. Ballasts) 'In particular, a full-bridge electronic ballast for a voltage-source (or current source) charging pump PFC circuit with continuous current mode. [Prior Art] φ With the advancement of lighting technology, electronic ballasts have gradually replaced electromagnetic ballasts (Electromagnetic ballasts) in the lighting market. Compared with electromagnetic ballasts, electronic ballasts have the advantages of small size, light weight and long life, and are very competitive in the lighting market. Therefore, electronic ballasts have great potential for development. However, in order to make the input current conform to the iec 61000-3-2 Class C specification, an electronic ballast with a power factor correction function is commonly used in lighting equipment. At present, the electronic ballast with power factor correction function is mainly in two stages (such as the first figure), and the two-stage electric luer ballast includes an AC input power source (providing an AC input voltage Vin), a filter, and a wave. Circuit (including inductor lemi and capacitor cEMI), a rectifier circuit (including diode Dbrl-Dbr4), a PFC stage (including inductor Lpfc, diode Dy and switch Spfc) and a full bridge inverter (including inductor Ls, capacitors CB and Cp, switches S1-S4 and lamps) have the following disadvantages: (1) More components are required, and the circuit cost is higher. (2) Both the power factor correction circuit and the power stage require a control IC, and the circuit is complicated. 3 201216781 In order to solve the above shortcomings, a half-bridge electronic ballast with a discontinuous current mode charging pump power correction circuit (such as the second figure) was developed. The half bridge electronic ballast with a discontinuous current mode charging pump power correction circuit includes a PFC stage (including a PFC stage including the AC input power source, the filter circuit and the rectifying circuit in the first step) A capacitor Cin and diode Dy), a half bridge inverter (including inductor Ls, capacitors CB and Cp, switches S1-S2 and the lamp) and a turn-out capacitor Cdc. However, the half-bridge electronic ballast with the discontinuous current mode charging pump due to the correction circuit still has the following disadvantages: (1) The circuit operates in the discontinuous conduction mode, and the input current has a large di/dt, electromagnetic miscellaneous The interference is more serious. (2) The circuit has a large peak current and must use circuit components with high current resistance. Since the half-bridge architecture is not suitable in many medium and high power lighting applications, the present invention combines continuous current mode charging pump power factor correction techniques (such as the third and fourth figures) with a full bridge electronic ballast. The equivalent circuit of the continuous current mode voltage source charging pump power factor correction circuit as shown in the third figure has a rectified DC voltage source (providing a rectified voltage 丨Vin| and a current Iin), a diode Dx And Dy, inductor Lpfc, capacitor Cin, voltage source (to provide a voltage Va), load and output capacitor Cdc, and one of the output capacitors Cdc across voltage unique output voltage Vbus. The equivalent circuit of the current source charging pump power factor correction circuit of the continuous current mode as shown in FIG. 4 is different from the third figure in that one diode Dx is missing, and the rectified DC voltage source is provided. A current lpfc, the current 201216781 capacitor Cin has a cross-connected power source Va is electrically connected in parallel with the diode body by a power generator, and thus is replaced by a turbulent output voltage Vbus.
