Since the connection point between the choke coil and the smoothing capacitor is connected to the load via the second diode, a leading phase current can flow and the input power factor can be improved. It is possible to reduce the drop in the voltage of the smoothing sigencer by separating it from the load by the diode, and also to reduce the output voltage difference due to the power supply frequency.Furthermore, by fully connecting the fifth diode to the choke coil VC+ffi column, Since the capacitor is connected in parallel to the series circuit including the choke coil, third diode, and smoothing capacitor, the current flowing through the capacitor increases the leading phase current7 and reduces the lagging phase current, further improving the input power factor. In addition, since a second choke coil is connected in series to one capacitor, the timing at which the phase-advanced current begins to flow can be made earlier, and the input power factor can be greatly improved, as well as the high-frequency components of the input current can be reduced. Furthermore, choke coil and %2
Because of the electromagnetic coupling between the choke coil and the coil, it is possible to increase the interface connected to the capacitor on the same side due to the mutual inductance between the poles, resulting in the effect that the power factor can be significantly improved.
