Definitions

  • the invention is related to led (light emitting diode) lighting, dimming, easy replacement of power current in small/medium power electronics.
  • the current control is carried out with constant resistors in the drivers that give a constant current like the led driver. Because resistors are a physical parts, it is not possible to change their value electronically.
  • the change of the digital current uses DALI (Digital Adressable Lighting Interface) system, which is more complex and cost effective than the invention.
  • DALI Digital Adressable Lighting Interface
  • the current at the output of the driver is constant and the electronic elements required for the creation of the drive are excessive, which creates a problem in terms of cost.
  • This invention allows the drivers to adjust the desired current value from the output section and make PF (power factor) correction easier.
  • drive currents can be produced in the desired form (sine, trapezoidal, square). Especially small power sources that provide compatible energy to the network make it easier to produce sine wave voltage.
  • the invention relates to led lighting, dimming, easy change of power current in small/medium power electronics, PF regulation and the current control circuit which transfers the desired current value to the device. It is characterized in that it has at least one mosfet (Metal Oxide Semiconductor Field Effect Transistor) to provide current control and/or to check the permeability of the current, at least one resistance for the stabilization of current to the drive and the PF regulation, and at least one drive which enables the regulation of PF and the connection of the current controlled current to the device.
  • mosfet Metal Oxide Semiconductor Field Effect Transistor
  • the dimming scheme is given in Figure 1, which consists of driver (1), resistor (2) and mosfet (3).
  • the voltage to mosfet (3) is‘O’, it is current-proof and closed.
  • RDS resistance between drain-source
  • the voltage to mosfet (3) is‘ G, the mosfet (3) lets the flow of the current, it is open.
  • RDS is in the minimum value here.
  • the voltage to mosfet (3) is between "0-1”
  • the RDS on mosfet (3) is variable and it will be possible to change between 10 milliohm and ⁇ ohm according to mosfet (3) type. In this way, current control will be possible since the total resistance will be R(1)+RDS.
  • resistance on Scheme (1) has been used in literature as resistance is expressed with‘R ⁇
  • Figure 2 shows the PF correction scheme, which consists of driver (1), resistor (2) and mosfet (3).
  • PF power factor
  • Dimming + PF correction scheme is given in Figure 3, this scheme consists of driver (1), resistor (2) and mosfet (3). In another exemplary use of the circuit, it can be used by connecting the connection part with "S" (source) leg of the mosfet (3) in the dimming circuit scheme and the driver (1) in the PF correction circuit diagram. In this way, current control can be controlled more precisely.
  • the ‘drain-source’ voltage is equal to the Sens control voltage (UCS) voltage, and because the UCS voltages are small (0.1 to 0.8 volts) due to the structures of the drives, the mosfet is naturally protected and these voltages are not sufficient to destroy the mosfet transistor if selected appropriately.
  • the invention allows easy dimming and energy saving by bringing PF closer to 1.0.
