专利汇可以提供Inverter circuit专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent application of excessive voltage to switching transistors by a method wherein applying voltages to the respective switching transistors of the doubly forward type inverter are controlled as to apply respectively the voltage of 1/2 of an electric power source voltage. CONSTITUTION:The light emitting diode D4, D5 sides of a pair of photo couplers PC1, PC2 connected in antiparallel are connected between the 1/2 voltage dividing point of the electric power source voltage and the series connecting point of the forward type inverters of two groups. Moreover, outputs of the photo transistors Tr3, Tr4 of the photo couplers PC1, PC2 are overlapped to a control voltage, which is input on one side of a comparator CMP being applied with a ramp wave voltage to an input terminal on another side, and with the control voltage to the same side terminal. The respective switching transistors Tr1, Tr2 are made to perform ON action alternately according to comparison output of the comparator CMP thereof.,下面是Inverter circuit专利的具体信息内容。
