Beschreibung
Zusammenfassung:	The invention discloses a direct current (DC)-DC convertor dead load which comprises a sampling resistor Ri, a control circuit, a power switch tube Q, a resistive load Rd, a load access terminal OUT- and a load access terminal OUT+. One end of the sampling resistor Ri is connected with an output cathode of a DC-DC convertor, an input negative terminal Cin- of the control circuit, an output negative terminal Cout- of the control circuit and an emitting electrode of the power switch tube Q, and the other end of the sampling resistor Ri is connected with the load access terminal OUT- of the DC-DC convertor and an input positive terminal Cin+ of the control circuit. An output positive terminal Cout+ of the control circuit is connected with a gate pole of the power switch tube Q. One end of the resistive load Rd is connected with a collector of the power switch tube Q, and the other end of the resistive load Rd is connected with an output anode of the DC-DC convertor and the load access terminal OUT+.
