<p>The converter has a switching power supply (U1) that is connected to a load (R6), and a direct current (DC) voltage is delivered to the load. A rectifier state buck chopper is connected upstream of the switching power supply, The rectifier stage buck chopper is connected to an input alternating current (AC) voltage source, and an output of the chopper is connected to an input of the switching power supply. The buck chopper provides a rectified voltage to the power supply, where the rectified voltage is lowered relative to AC voltage of ground input.</p> |
