As shown in Figure 1, the vehicle-mounted High Power Microwave System of hybrid power supply described in the utility model, comprise vehicle-mounted High Power Microwave System, it is characterized in that, also comprise controller, switches set, batteries, inverter and generator, described controller is connected with vehicle-mounted High Power Microwave System and switches set respectively, and described switches set is connected with vehicle-mounted High Power Microwave System, generator, inverter and batteries respectively; Described controller produces synchronous control signal according to the high power microwave radiation characteristic of vehicle-mounted High Power Microwave System, this synchronous control signal produces corresponding microwave signal for vehicle-mounted High Power Microwave System on the one hand, on the other hand for control switch group: in the time that this synchronous control signal is high level, diesel engine generator is vehicle-mounted High Power Microwave System power supply by switches set, and batteries is vehicle-mounted High Power Microwave System power supply through inverter and switches set simultaneously; In the time that this synchronous control signal is low level, diesel engine generator and batteries are all without powering to vehicle-mounted High Power Microwave System, and now diesel engine generator is battery charging by switches set.
Operation principle of the present utility model is:
Vehicle-mounted High Power Microwave System consists predominantly of and produces the microwave signal control module that transmits of microwave and the transmitter of launched microwave, microwave signal control module produces pulse control signal, control transmitter and carry out microwave transmitting, signal produces rear by being launched by transmitter after a series of circuit (as amplifying circuit), the control signal of controller of the present utility model is synchronizeed with the microwave emissioning controling signal of vehicle-mounted High Power Microwave System, realize this synchronous control signal and have several different methods, as controller and micro-signal control module adopt identical control clock, adopt identical concussion frequency to produce identical pulse signal, or the control signal of controller produces end and directly adopts the clock signal of microwave emission control module all can realize synchronously, when object is to make microwave system launched microwave, hybrid power supply device has completed the conversion of supply module under the control of controller, for microwave system provides electric energy.
As shown in Figure 2, the work of the transmitter of vehicle-mounted High Power Microwave System is pulse or quasi c. w. pattern, therefore the microwave signal reflector launched microwave in the transmitter of vehicle-mounted High Power Microwave System is worked according to certain rules, according to the time response of microwave transmitting, in the time that launching, microwave signal controls batteries power supply, in the time that microwave signal generator stops, controlling generator is battery charging, thereby realizes the object that extends System production time.Wherein, controller produces synchronous control signal according to the high power microwave radiation characteristic of vehicle-mounted High Power Microwave System, this synchronous control signal produces corresponding microwave signal for vehicle-mounted High Power Microwave System on the one hand, on the other hand for control switch group: in the time that this synchronous control signal is high level, diesel engine generator is vehicle-mounted High Power Microwave System power supply by switches set, and batteries is vehicle-mounted High Power Microwave System power supply through inverter and switches set simultaneously; In the time that this synchronous control signal is low level, diesel engine generator and batteries are all without powering to vehicle-mounted High Power Microwave System, and now diesel engine generator is battery charging by switches set.
As shown in Figure 3, for the batteries mode of operation corresponding with the transmitter mode of operation of vehicle-mounted High Power Microwave System, in the time of the transmitter launched microwave of vehicle-mounted High Power Microwave System, be the transmitter power supply of vehicle-mounted High Power Microwave System, charging in the time that the transmitter of vehicle-mounted High Power Microwave System stops.
Wherein, diesel engine generator is worked always, for emission system provides primary energy, maintaining emission system normally works, batteries provides energy supplement through inversion for emission system, only in the time of outside radiation signal, work, and stand-down diesel engine generator be battery pack makeup energy.
Setting vehicle-mounted High Power Microwave System instantaneous radiation power is P kw, and system power supply efficiency is η, and power supply instantaneous power is PS=P/ η.If adopting diesel engine generator is separately vehicle-mounted High Power Microwave System power supply, require the instantaneous apparent power of generator to be not less than PS; Adopting batteries is separately vehicle-mounted High Power Microwave System power supply, requires the apparent instantaneous power of inversion to be not less than PS, and inversion efficiency is η 1, and inverter voltage is V1, and the electric current that flows through battery pack is:

Therefore adopt the utility model, after onboard system oil plant exhausts, storage battery still can, for system provides power, extend System production time.
If vehicle is fully loaded with diesel oil L liter, incendivity produces electric energy U joule, owing to adopting hybrid power supply, if P1≤PS adopts the system operable time of hybrid power to extend; If adopt hybrid power power supply simultaneously, in the time that diesel oil exhausts, batteries still can be maintained system works, and the time is depended on the power capacity of battery energy storage capacity and inverter.
Take the High Power Microwave System of a radiation 20KW as example
If when generator is powered separately, if High Power Microwave System efficiency is 20%, generator apparent power=100KW, considers that generator power factor is 0.8, and generator generating capacity is not weaker than 125KW.
If while adopting battery pack to power separately, inverter output apparent power=100KW, if inversion efficiency 80%, the instantaneous power that provides of battery pack is 125KW, adopt 48V battery pack to carry out three-phase inversion, every group of electric current=125kw/3/48=0.858KA, if each battery pack overcurrent is limited in 500A, needs two groups of also process current equalizers in parallel that so large electric current is provided.
If adopt 50kw generator powered and batteries hybrid power supply mode, consider that generator power factor is 0.8, generator generating capacity is not weaker than 62.5KW, as the diesel engine generator parameter of table 1, volume, weight, the more independent diesel engine generator power supply of noise reduce more than 1/3, if inversion efficiency 80%, the instantaneous power that provides of battery pack is 62.5KW, adopt 48V battery pack to carry out three-phase inversion, every group of electric current=62.5kw/3/48=0.434Ka, if each battery pack overcurrent is limited in 500A, only need a Battery pack group that so large electric current is provided.As table 2 high-energy battery parameter, volume weight can reduce half.
