A high-strength ignition coil that can reduce stress produced in a coil case and prevent a casting material from being cracked when the ignition coil is mounted on an engine block. A coil case has a mounting flange on an outer surface thereof. A coil assembly is housed in the 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. A plurality of first guide ribs are provided on an inner wall surface of the coil case or an outer surface of the coil assembly, for positioning the outer surface of the coil assembly with respect to the inner wall surface of the coil case. A limited area in which there is no first guide rib is provided on the inner wall surface of the coil case which faces the mounting flange, or the outer surface of the coil assembly which faces the mounting flange via the inner wall surface of the coil case.

摘要:
A power supply apparatus for a welder includes a rectifier (104) and a smoothing reactor (106) which operate together to convert a commercial AC supply voltage to a DC voltage. The DC voltage is converted to a high-frequency voltage by an inverter (108), which, in turn, is voltage-transformed by a voltage-transformer (110). The voltage-transformed, high-frequency voltage is converted to a DC voltage by a rectifying diode (112) and a smoothing reactor (114), and the resulting DC voltage is applied to a workpiece (118a) and a torch (118b). A current detector (120) develops a load current representative signal, and a control circuit (122) so controls a drive circuit (126) which drives the inverter (108) that the load current representative signal becomes equal to a reference current signal provided by a reference source (124). When a small load current is used, a pulse forming switch (140) is repetitively turned on and off to produce a pulse current from a pulse current setting source (139). The pulse current is superposed on a control signal from the control circuit (122).
摘要:
A power supply apparatus for use with an arc utilizing device includes capacitors coupled in series between outputs of a rectifying unit, and inverters each of which is coupled across a respective one of the capacitors. Each inverter converts a DC voltage from the capacitor into a high frequency voltage and applies it to a respective one of transformers. A converter converts an output voltage from each transformer into a DC voltage for application to a load. An output detector generates a signal representative of an output current supplied to the load. A first voltage detector generates a signal representative of a first voltage to be applied to the inverters. A second voltage detector generates a signal representative of a second voltage across one of the capacitors. A voltage balancing unit generates control signals for determining the conduction periods of the respective inverters in accordance with the difference between the output representative signal and a preset desired-output-current representative signal. The voltage balancing unit modifies at least one of the control signals to change the conduction period of the inverter associated therewith in accordance with the difference between the first- and second-voltage representative signals.
