Definitions

  • An effective winch controller should protect not only the motor, but also the control circuitry, battery storage and have sufficient power to recover all types of vehicles. It should also be efficient, reliable and cost effective. A need remains for such a device.
  • the invention is a solid state relay controller that when configured as a full bridge can be used as a winch controller. When configured as a half bridge the relay of the subject invention can be used as a battery isolator/separator.
  • the solid state relay is unique in that it contains independent charge pumps that isolate each gate of the bridge individually to achieve faster and proper gate turn on.
  • the low side MOSFETs are used as the current sensing device and for thermal compensation protecting the solid state relay as well as the controlled device.
  • N-channel MOSFETs are used to configure the bridge. N-channel MOSFETs offer the unit higher amperage and reduce cost of the device.
  • a preferred embodiment of the subject relay offers dynamic braking by providing a load across the motor allowing the motor to act as the brake.
  • FIG. 1 is a schematic diagram of a preferred embodiment of the solid state relay of the subject invention featuring wireless two-way communication.

  • FIG.5 is a schematic diagram of another preferred embodiment of the solid state relay of the subject invention configured for use as a battery isolator/separator.
  • a solid state relay controller provides independent charge pumps to isolate each gate individually to achieve fast and proper gate turn-on.
  • the subject controller prevents the unit from overheating damaging the controlled device.
  • MOSFETs are driven by switching.
  • heat is generated as the MOSFET goes from a high resistive state to a low resistive state.
  • the heat generated by switching MOSFETs creates a significant problem.
  • a winch requires current loads as high as 500 amps, with continuous current loads required in the 210 amp range, or higher. The heat generated by these loads can destroy the winch motor as well as damage the control circuit.
  • the solid state relay controller of the subject invention is different in that it drives circuit MOSFETs individually. Both high side and low side MOSFETs are driven separately allowing the gates to be fully turned on. Since the MOSFETs are fully conducted during their entire operation, and are not being switched on and off, the subject relay supports high current loads while generating very little heat. Additionally, electric motor impedance and inductance which also affect performance when switching high current loads are inconsequential when the gates are driven separately. The impedance and inductance of an electric motor greatly affect the high side gate of N channel MOSFETs causing the high side MOSFETs to not conduct fully and generate much heat. The electric motor therefore does not get the proper voltage and current needed to achieve maximum performance.
  • the subject system uses the low side MOSFETs as a current sensing device and thermal compensation greatly minimizing voltage loss. By measuring the voltage across the low side MOSFETs in conjunction with a current monitoring circuit thermal protection/thermal compensation for the MOSFETs, as well as the motor, battery, and cables are provided.

  • a resistor feedback network stabilizes hysteresis.
  • a slave network of two transistors, a plurality of resistors, and a buffer capacitor shut down the MOSFETs when the current exceed the threshold current setting.
  • PWM ICs 30 regulate and control the voltages to the gate of the MOSFETs. Thermal compensation is achieved by the two lower MOSFETs working as a current sensing device and in conjunction with the current sensing circuit.

  • Motor stall sensing through a stall detection circuit 32 prevents motor damage should the motor 40 stall.
  • Motor temperature sensing is achieved by checking impedance of the motor at microsecond pulses of the motor to see if it is getting hot.
  • the motor stall detection circuit 32 can be eliminated and motor protection can be achieved by measuring current and using a thermal model 38 in conjunction with the microprocessor 30 and a programmed instruction set (i.e. software).

Abstract

L'invention concerne un relais statique doté de pompes de charge indépendantes isolant chaque grille d’un pont complet afin de réaliser une activation correcte et accélérée des grilles. Les MOSFET du côté bas du pont constituent le dispositif de détection de courant, réduisant les pertes et permettant à un dispositif commandé par le relais d’atteindre des performances maximales. Le freinage dynamique est réalisé en plaçant les deux MOSFET côté bas à l’état pleinement passant et en appliquant une charge aux bornes du moteur à CC. L’ajout d’un microprocesseur au dispositif assure la détection de sous-tension, des indications de courant en fonction du temps, la détection du calage du moteur et la détection de la température du moteur. La température du moteur est détectée en contrôlant l’impédance du moteur à des impulsions de l’ordre de la microseconde pour déterminer si le moteur s’échauffe.
