Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, in addition to mutually exclusive feature and/or step, all can combine by any way.
As shown in Fig. 1, the squarer of the present invention, mainly it is made up of two parts, one is that rectangular pulse forms line T1, pulse-forming line T1 is made up of inner core and the crust being wrapped on inner core, inner core is charging positive pole, and the two ends of inner core are commonly connected to switch one end of K, and the other end of switch K is connected to earth potential.Rectangular pulse forms line T1 inner core wherein one end and connects charge power supply, rectangular pulse is formed and is connected a current limliting and isolation resistance Rc between line T1 and charge power supply, resistance Rc is the charging current limiter resistance that rectangular pulse forms line T1, can limit maximum charging current by it；Simultaneously when switching K and disconnecting, can be with the pulse of the isolation rectangular pulse-forming line T1 two ends generation impact to power supply.
Another part of the present invention is power combing part, and this part includes that two transmission line pulse power combing transmission line T2, pulse power synthesize transmission line T3, and it is identical that the structure of two transmission lines forms line with rectangular pulse；Rectangular pulse forms the crust of line T1 one end and connects the inner core that pulse power synthesizes transmission line T2, rectangular pulse forms the crust of the line T1 other end and connects the inner core that pulse power synthesizes transmission line T3, and pulse power synthesis transmission line T2, the other end of pulse power synthesis transmission line T3 are linked together by wire.Wire one end is connected to the inner core of pulse power synthesis transmission line T2, and the other end is connected to the crust of pulse power synthesis transmission line T3.Connect at pulse power synthesis transmission line T3 and on the inner core of wire one end, connect output loading.
