Patent ID: 8810143

Claim:
A control system, comprising: a detection circuit for detecting a level switch of a direct-current voltage, the detection circuit outputting an activating signal when the detection circuit detects the level switch of the direct-current voltage, wherein the detection circuit comprises: a capacitor comprising a first terminal and a second terminal, wherein the first terminal of the capacitor receives the direct-current voltage; a first resistor comprising a first terminal and a second terminal, wherein the first terminal of the first resistor is electrically connected to the second terminal of the capacitor, and the second terminal of the first resistor is connected to ground: a second resistor comprising a first terminal and a second terminal, wherein the first terminal of the second resistor is electrically connected to the second terminal of the capacitor; and a third resistor comprising a first terminal and a second terminal, wherein the first terminal of the third resistor is electrically connected to the second terminal of the second resistor, and the second terminal of the third resistor is connected to ground; a control circuit for receiving the activating signal; and a dummy load system electrically connected to the control circuit, wherein the control circuit generates a turn-on signal in response to receiving the activating signal to control the dummy load system.
