The invention relates to a power output technology, in particular to an output switching circuit which comprises two independent power output units, a first power conversion unit branch, a second power conversion unit branch, an output diode and a control switch. According to the output switching circuit, full-range constant power output can be achieved by controlling on-off of the switches, due to the fact that the two independent units bear half of the output power respectively, device selection is easy, consumption can be reduced, efficiency can be improved, only one control switch is used, a traditional output switching circuit needs three switches, and the cost is low. Under the condition that the through-flow of the diodes and the through-flow of the switches are the same, the output switching circuit does not use two switches, the circuit control difficulty is reduced, and the cost is reduced. 本发明涉及功率输出技术，尤指一种输出切换电路，包括两个独立的功率输出单元，第一功率变换单元支路和第二功率变换单元支路，以及输出二极管和控制开关。本发明的输出切换电路可通过控制开关的通断来实现全范围的恒功率输出，且由于两个
