Patent number: 11271385Abstract: An abnormal-voltage protection apparatus includes a switch unit, a voltage detection unit, and a delay time control unit. The switch unit is coupled to a power supplying path formed between an AC power source and a load. The voltage detection unit detects the AC power source and provides a detection signal. The delay time control unit is coupled to the voltage detection unit and the switch unit, and receives the detection signal and provides a control signal to the switch unit according to the detection signal. When the voltage detection unit detects that the AC power source changes from an abnormal voltage to a normal voltage, the delay time control unit turns on the switch unit by the control signal after a delay time so that the AC power source supplies power to the load through the power supplying path.Type: GrantFiled: November 5, 2018Date of Patent: March 8, 2022Assignee: DELTA ELECTRONICS, INC.Inventors: Yu-Chieh Tseng, Chia-Hao Yeh, Likai Lin

Patent number: 9667055Abstract: An over-voltage protection apparatus includes an input voltage detection module (12) and a second switch (14). The input voltage detection module (12) includes a switch assembly (121), a rectifying circuit (122), a voltage detection circuit (123), and a voltage protection circuit (124). The rectifying circuit (122) rectifies an AC power source (Vac) to generate a DC voltage (Vb). The voltage protection circuit (124) controls the second switch (14) to disconnect the AC power source (Vac) to supply a load (90) when the voltage detection circuit (123) detects that the DC voltage (Vb) reaches to a first over voltage value (Voth1). The voltage protection circuit (124) controls the switch assembly (121), thereby providing a voltage-limiting protection and a current-limiting protection when the voltage detection circuit (123) detects that the DC voltage (Vb) reaches to a second over voltage value (Voth2).Type: GrantFiled: February 26, 2015Date of Patent: May 30, 2017Assignee: DELTA ELECTRONICS, INC.Inventors: Yu-Chieh Tseng, Chien-Chung Lee, Chia-Hao Yeh

Patent number: 8879293Abstract: A cooling system of a server with an AC power source and a DC power source includes an AC input subsystem, a DC input subsystem, and a driving control subsystem. The AC input subsystem receives an external AC power source and provides a first DC voltage and a second DC voltage. The DC input subsystem receives an external DC power source and provides a third DC voltage and a fourth DC voltage. When the external AC power source normally works, the driving control subsystem controls the first DC voltage and the second DC voltage to supply a high-voltage cooling apparatus and a low-voltage cooling apparatus, respectively. When the external DC power source normally works, the driving control subsystem controls the fourth DC voltage and the third DC voltage to supply the high-voltage cooling apparatus and the low-voltage cooling apparatus, respectively.Type: GrantFiled: January 17, 2013Date of Patent: November 4, 2014Assignee: Delta Electronics, Inc.Inventors: Yen-Chang Chen, Chien-Chung Lee, Chen-Yu Huang, Yu-Chieh Tseng
