Definitions

  • a power board is often used to power those individual elements. It is another object of this invention to provide an intelligent power board which may be used as a conventional power board, but which is also adapted to manage the supply of power to the PC and such peripheral devices.
  • the invention provides apparatus for the supply of electrical power to at least two units, one of said two units being defined as a master unit and the other or others of said two units being defined as a slave units or as slave units, said apparatus being adapted to be electrically connected to said master unit and to said slave unit or slave units, said apparatus including sensing means adapted to sense the state of said master unit, the state being the said master unit is switched on or switched off, and a switching device for switching power to said slave unit or slave units on or off as a result of the state sensed by said sensing means.
  • said apparatus also includes control and/or logic devices for processing the output from said sensing device prior to applying said output to said switching device.
  • said sensing means is a series resistor, or a magnetic field device such as a magneto resistor or a Hall effect sensing element.
  • said current transformer is adapted to supply electrical power to other components of said apparatus.
  • said switching device is a relay or a triac.
  • said apparatus is a power board, with a master outlet for said master unit, and one or more slave outlets for said or each slave units.
  • Fig. 3 is a circuit diagram of a third embodiment of the present invention, a more sophisticated, advanced, master-slave or intelligent power board.
  • the form of the socket is that used in Australia for 240V AC supply at 50Hz/60Hz, and that the three-pin plugs connected to electrical devices (not shown) are complementary; it is to be understood that that form will vary on accordance with the plug/socket designs of the jurisdiction concerned. In addition, in other jurisdictions the supply may be other than 240V, at 50Hz/60Hz.
  • a slave device or slave devices (in the described embodiments a computer peripheral device or a number of computer peripheral devices (not shown)) is/are intended to be plugged into the slave socket (one of 12, 14, 16), or into a respective one of said slave sockets (12, 14, 16).
  • the master socket 10 is supplied with electrical power via a sensing unit 18 located in the housing (not shown) of the power board, which sensing unit 18 detects the current drawn by the computer when it is switched on.
  • the power board also includes a processor 20, and a switching device 22, which switching device 22 is turned on by the processor 20 circuitry when the circuitry determines that the computer has been switched on. This is the situation represented by the basic circuit of Fig. 1.
  • the master-slave power board circuit may consist of a current-operated relay.
  • a current transformer may be used to drive the sensing unit 18, and the operating power derived from transformer output; this would reduce the drop in voltage to the master unit, caused by the sensing device, and reduce the current through the sensing unit to a more convenient level.
  • D4 is preferably a Zener diode, and keeps the voltage approximately constant.
  • Resistor R5 limits the current flowing through C2, if the power initially switched on at, or near, the peak of the supply voltage waveform.
  • the third embodiment of a power board according to the present invention whose circuit is shown in Fig. 3, is more sophisticated than that of Fig. 2.
  • Diodes D1 and D2 and triacs Tr1 and Tr2 detect the current drawn by the computer (not shown, but in use plugged into master socket 10), as described in relation to the Fig. 2 embodiment, and charges capacitor C2.
  • Resistor R3 and capacitor C2 provide an additional time delay to guard against triggering from transient disturbances.
  • Q1 is one section of a quad 2 input Schmitt trigger Nand logic gate, and is connected as an inverter. When the computer is switched off, the output is low. When the computer is switched on, the output will suddenly switch to +8V, after the delay determined by R3 and C2. Triacs Tr3 and Tr4, and resistors R4 and R5, are connected as a zero crossing detector. Normally either Tr3 or Tr4 is turned on, and the collectors are held low. However, each time the voltage between active and neutral reverses, both transistors are momentarily turned off, causing a brief positive pulse to appear across resistor R5. This positive pulse is applied to one input of Q2, and if the computer is switched on, and the other input is also high, the output of Q2 will go low.

Abstract

L'invention se rapporte à une carte intelligente de distribution de puissance conçue pour alimenter un ordinateur personnel et un certain nombre de ses périphériques. Cette carte comporte une sortie maître (10) sur laquelle l'ordinateur peut être branché, et une sortie asservie (12, 14, 16) sur laquelle différents dispositifs périphériques peuvent être branchés. La distribution de puissance aux sorties asservies (12, 14, 16) est commandée par un commutateur (22). Cette carte de distribution de puissance comporte un dispositif de détection (18) qui détecte si l'ordinateur est sous tension ou non. Un processeur (20) traite les informations en provenance du dispositif de détection (18) et bascule le commutateur (22), en fonction de la nature de ces informations, de manière à le placer en position ouverte ou fermée, et donc de manière à activer ou non l'alimentation en électricité des sorties (12, 14, 16) et à alimenter ou non les dispositifs périphériques branchés sur ces sorties (12, 14, 16).
