Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains.

Claims 1-2, 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over Yang et al. (Pub. No. 20110181236 A1) in view of Yan et al. (Pub. No. 20190245432 A1).
Regarding claims 1, 19, and 20, Yang discloses:

a first power conversion circuit (see Fig.1, illustrate below, conversion 110) comprising:
a second end coupled to the first end (see Fig., see illustrate below); and
a third end (see Fig., see illustrate below, third end connects to AC power supply),
wherein the first power conversion circuit is configured to (see Fig.1, Fig below, conversion 110):
when the electric vehicle is in a charging mode (see par [0048-0050], The high-voltage charging controller 130 controls the first rectifying portion 110 and second rectifying portion/inverter 120 and charges a high-voltage in the high-voltage battery BAT1 in the charging mode…., see par [0053]): and
when the electric vehicle is in a driving mode: (see illustrate below, par [0050-0053], The low-voltage charger 150 charges a low-voltage in the low-voltage battery BAT2 using power charged in the high-voltage battery BAT1….[wherein the high-voltage BAT1 is direct current and convert to a direct current low-voltage BAT2]); and
supply the converted current to the low-voltage system, and wherein when the electric vehicle is in the driving mode (see illustrate below, par [0050-0053], The low-voltage charger 150 charges a low-voltage in the low-voltage battery BAT2 using power charged in the high-voltage battery BAT1….[wherein charging the low-voltage battery BAT2 which is the converted current to the low-voltage has been supplied]),
the second power conversion circuit is configured to (see illustrate below):
convert a high voltage of the power battery pack into a low voltage (see illustrate below, par [0050-0053], The low-voltage charger 150 charges a low-voltage in the low-voltage battery BAT2 using power charged in the high-voltage battery BAT1….);
transmit the low voltage to the first low-voltage output end; and output the direct current to the first power conversion circuit (see illustrate below, par [0050-0053], The low-voltage charger 150 charges a low-voltage in the low-voltage battery BAT2 using power charged in the high-voltage battery BAT1….).

However, Yang fails to disclose:
convert an alternating current input from the third end into a direct current; and transmit the direct current to the first end
perform direct current conversion on the direct current to obtain a converted current; and
an electromagnetic interference (EMI) filter circuit comprising: an input end coupled to the alternating current input; and an output end coupled to the third end, wherein the EMI filter circuit is configured to filter out electromagnetic interference.
Thus Yan discloses:
convert an alternating current input from the third end into a direct current (see Fig. 1, illustrate below); and transmit the direct current to the first end (see Fig. 1, illustrate below, see par [0059], The rectifier module is configured to convert AC power into DC power and output it on the DC bus…..)
perform direct current conversion on the direct current to obtain a converted current (see Fig. 1, illustrate below, see par [0059],The DC-DC converter module converts the DC power on the DC bus into a DC output that can be used by the load; and
an electromagnetic interference (EMI) filter circuit comprising (see Fig. 1, illustrate below. EMI filter, see par [0059], The ground charger mainly includes an EMI (Electro Magnetic Interference) filter, a rectifier module and a DC-DC converter module. The EMI filter is configured to filter interference in the AC input from the power grid….): an input end coupled to the alternating current input; and an output end coupled to the third end, wherein the EMI filter circuit is configured to filter out electromagnetic interference (see Fig. 1, illustrate below. EMI filter, see par [0059], The ground charger mainly includes an EMI (Electro Magnetic Interference) filter, a rectifier module and a DC-DC converter module. The EMI filter is configured to filter interference in the AC input from the power grid….).
It would have been obvious to one of ordinary skill in the art at the time the invention was made to have modified a charger including a first rectifying portion that rectifies an alternating power of Yang to include an EMI filter in order to filter interference in the AC input (see Yan par [0059]).
