Intrinsically safe power conditioning circuit

The invention discloses an intrinsically safe power conditioning circuit. A power conditioning circuit (105) includes at least one power storage device 110 having electrodes 110a, 110b coupled for receiving power from a DC power source 160. At least one active current limit (ACL) circuit 115a, 115b, 115c coupled to the electrodes of the power storage device for limiting a maximum power output from the power storage device under fault conditions. A DC-to-DC converter 120 has its inputs coupled to the ACL circuit. At least one crowbar circuit 130a, 130b has a first terminal and a second terminal and a shorting device coupled to an output of the DC-to-DC 120 converter for providing output terminals 131, 132 for the power conditioning circuit (105). 公开了种本质上安全的功率调节电路。功率调节电路（105）包括至少个功率存储设备110，至少个功率存储设备110具有被耦接以用于从DC功率源160接收功率的电极110a、110b。至少个有源电流限制（ACL）电路115a、115b、115c耦接到功率存储设备的电极以用于在故障状况下限制从功率存储设备输出的最大功率。DC至DC转换器120使其输入耦接到ACL电路。至少个消弧电路130a、130b具有第端子和第二端子以及耦接到DC至DC 120转换器的输出以用于为功率调节电路（105）提供输出端子131、132的短路设备。
