    • A high-strength ignition coil that can prevent distortion arising from pin marks formed on a surface of a core and makes it less likely for insulating resin to be cracked. The coil assembly is housed in a coil case. A casting material is filled into a gap between the coil case and the coil assembly and gaps which the coil assembly has. The coil assembly is comprised of a coil pair including a cylindrical primary coil and a secondary coil disposed concentrically with the primary coil, and a core. The core is fitted into a central space of the coil pair and forms a magnetic path. The core is coated with mold resin. Concave portions of pin marks formed on a mold resin coating by removal of core fixing pins when the mold resin coating is formed are filled with mold resin.

    • A welder power supply apparatus (10) includes an inverter (20), which is driven intermittently when an electrode (34) and a workpiece (36) are separated from each other and no arc is being generated between them, whereby power loss generated in the inverter (20) when the inverter (20) is driven in the non-load state of the power supply apparatus and power loss caused by exciting current flowing through an transformer (24) disposed in the output of the inverter (20) can be reduced. The inverter (20) is driven continuously when output current (Io) becomes higher than a threshold value (Ib) after the electrode (34) and the workpiece (36) are brought into contact with each other for starting arcing between them. In this manner, the arcing can be initiated without fail.

    • An input-side rectifier rectifies a commercial AC voltage from a commercial AC power supply connected to an input terminal and develops a rectified voltage between two output terminals. The rectified voltage is smoothed by a pair of capacitors. A switching arrangement connects the capacitors selectively in series and in parallel between the two output terminals. An inverter is associated with each of the capacitors. A high-frequency voltage from each of the inverters is voltage-transformed by a transformer. The high-frequency voltage from the transformer is converted into a DC voltage by a high-frequency-to DC converter for application to a load. When an AC voltage in a lower voltage group is applied to the input terminal, a switching control unit causes the switching arrangement to connect the capacitors in parallel, and when an AC voltage in a higher voltage group is applied to the input terminal, the switching arrangement is caused to connect the capacitors in series. The inverters include IGBTs having a withstanding voltage of about 800 V.
    • 输入侧整流器从连接到输入端的商用AC电源整流商用AC电压,并在两个输出端之间产生整流电压。 整流电压由一对电容器平滑。 开关装置将电容器选择性地串联并联在两个输出端子之间。 逆变器与每个电容器相关联。 来自每个逆变器的高频电压由变压器进行电压变换。 变压器的高频电压通过高频至直流转换器转换为直流电压,用于负载。 当将较低电压组中的AC电压施加到输入端时,开关控制单元使开关装置并联连接电容器,并且当较高电压组中的AC电压施加到输入端子时,开关 使电容串联连接。 逆变器包括具有约800V耐受电压的IGBT。
