专利汇可以提供Regulated dc to dc converter with regulated current source driving a nonregulated inverter专利检索，专利查询，专利分析的服务。并且A regulated DC to DC converter comprises a switching-type regulated current source driving a non-regulated bridge-type inverter. The output signal of the converter is regulated by pulse width modulating the switching device in the switching regulator. The output impedance of the current source is inductive. This inductive impedance, which comprises the freewheeling or flyback inductor of the switching regulator, operates as the principal filter inductor of the converter. This regulator-inverter combination advantageously simplifies the switching control of the inverter switching devices and reduces the switching losses therein. It eliminates the switching control problems which normally occur due to switchthrough phenomena and the saturation of the inverter transformer.，下面是Regulated dc to dc converter with regulated current source driving a nonregulated inverter专利的具体信息内容。
