Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1～3, a kind of power saving driving structure that is used for the fuel cell electromagnetic element comprises the economize on electricity drive circuit, this circuit is when electromagnetic element is opened, export specified driving voltage and give electromagnetic element, after electromagnetic element was opened, output was given electromagnetic element a little more than the voltage of keeping of release voltage.
After deliberation, general Electromagnetic Drive element, after action, the magnetic circuit closure only needs lower electric current just can keep its state, and for example the operation voltage of most of relays is 75% of its line bag nominal drive voltage, but release voltage only is 25%.
For solenoid valve, because it is moving that solenoid valve is inhaled iron block in order to overcome hydrodynamic pressure, often leave bigger surplus, above-mentioned OK61A solenoid valve, when working pressure very little (for example 0.1Bar), operation voltage is 3.5V, and when working pressure big slightly (for example 1.5Bar), operation voltage also only is 4.5V.Its release voltage is extremely low, only is 0.2V, and almost irrelevant with working pressure.
Therefore, can when requiring solenoid valve (or other electromagnetic element) to open, provide nominal drive voltage, subsequently driving voltage be reduced to a little more than release voltage to it.When requiring it to close, again driving voltage is removed.
Implement the device of said method, can place outside the electromagnetic element, also can be integrated within the electromagnetic element.
Embodiment 1
As shown in Figure 1, when the circuit module of being defeated by from the nominal drive voltage of fuel cell system control circuit among the figure, the PWM controller is defeated by field effect transistor with the signal of 100% pulsewidth, drives the solenoid valve action.Subsequently, the pulsewidth of PWM controller descends, and the average voltage that acts on solenoid valve descends, and average current descends, but still a little more than release voltage, solenoid valve is held open state.Stop to provide nominal drive voltage, closed electromagnetic valve until the fuel cell system control circuit.When opening, the PWM controller can start from full pulsewidth again, reduces pulsewidth then next time.
Embodiment 2
As shown in Figure 2, when the circuit module of being defeated by from the nominal drive voltage of fuel cell system control circuit among the figure, delay switch circuit is opened, the solenoid valve action, at this moment, diode reverse by.Subsequently, delay switch circuit disconnects, the diode forward conducting, and lower the keeping voltage and keep electric current that miniature DC-DC provides offers solenoid valve.Stop to provide nominal drive voltage, closed electromagnetic valve until the fuel cell system control circuit.
Embodiment 3
As shown in Figure 3, if the start and stop of fuel cell system are not frequent, even can adopt PTC to realize.Certainly, because PTC has certain power consumption, energy-saving effect can be slightly poor.In addition, keep voltage and keep the accuracy of electric current, also can be weaker.
