Embodiment Construction
[0030] The constant current source circuit with current monitoring according to the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
[0031] When the constant current source circuit is working, if the output current is monitored in real time, when the output current is abnormal and larger than the design value, the power supply of the constant current source will be cut off immediately, so that the protection of the electrical equipment can be realized.
[0032] Based on this, if figure 1 As shown, the constant current source circuit with current monitoring according to the present invention includes a basic constant current source circuit 1, a current detection circuit 2, a voltage conditioning circuit 3, a comparison circuit 4, a signal holding circuit 5, a power supply control circuit 6, and a power conversion Circuit 7. Among them, the power conversion circuit 7 receives the external power supply,...
