专利汇可以提供Square wave driven power amplifier专利检索,专利查询,专利分析的服务。并且A high power semiconductor amplifier which may be used as a power amplifier for low frequency apparatus such as radio transmitters and/or welding apparatus. A plurality of transistor driven amplifier sections are commonly driven by a square wave source and are coupled in parallel to a common load through loosely electro-magnetic coupled transformers or inductances forming the power combiner circuit. The loose coupling provides a desired low distributive capacitance and high leakage inductive reactance. Each amplifier driver section moreover is coupled to the transformer by a DC blocking capacitor having a selected capacitance value so that a series resonant circuit is formed with the combiner circuit leakage reactance near the center of the operating frequency band. Furthermore, the combiner circuit is coupled to the load by means of a harmonic filter having a series inductance input which acts to present a high reactive impedance to harmonics in the square wave voltage applied thereto so that a substantially sine wave of voltage and current is applied to the load.,下面是Square wave driven power amplifier专利的具体信息内容。
