摘要： A DC voltage from a DC supply is applied to inverters of two power supply units connected in parallel with each other. The inverters convert the received DC voltages into high-frequency voltages, which are, in turn, voltage-transformed in transformers. The outputs of the transformers are rectified in two rectifiers, respectively, and smoothed in two reactors. The smoothed voltages are supplied between output terminals. The reactors are formed on a single core, being loosely coupled with each other.

摘要： A DC power supply apparatus includes a rectifier circuit which rectifies an input commercial AC voltage. The rectifier output voltage is smoothed in a smoothing capacitor. The DC voltage from the capacitor is converted to a high-frequency voltage in an inverter. The high-frequency voltage from the inverter is voltage-transformed by a transformer into a voltage-transformed, high-frequency voltage, which is then converted back into a DC voltage in a high-frequency-to-DC converter circuit. When an input commercial AC voltage is applied to the DC power supply apparatus, a pre-charging circuit pre-charges the smoothing capacitor from the input AC voltage. If a voltage having a magnitude larger than a prescribed value is applied to the DC power supply apparatus, an overvoltage protection circuit renders the rectifier circuit and the pre-charging circuit inoperative.

摘要： A DC power supply apparatus has two power supply input terminals between which one of 100 V level, 200 V level and 400 V level AC power supply voltages or a 575 V AC power supply voltage is applied. A rectifying unit is connected between the two power supply input terminals, and a voltage-lowering converter is connected to the rectifying unit. A thyristor is connected between the input and output of the voltage-lowering converter. A series combination of two capacitors is connected between two output terminals of the voltage-lowering converter. A switch circuit is connected between the junction of the two capacitors and one input terminal of the rectifying unit. An inverter converts a DC voltage appearing across the series combination of the capacitors into a high-frequency voltage, which, in turn, is voltage transformed by a transformer. The voltage-transformed high-frequency voltage is converted into a DC voltage in a high-frequency-to-DC converter for application to a load. When a 100 V level voltage is applied between the power supply input terminals, the thyristor is turned on, the voltage-lowering converter is turned off and the switch circuit is turned on. When one of the 200 V level voltages is connected, the thyristor is turned on, the voltage-lowering converter is turned off, and the switch circuit is turned off. When one of the 400 V level voltages or the 575 V voltage is applied between the power supply input terminals, the thyristor is turned off, the voltage-lowering converter is turned on, and the switch circuit is turned off.

摘要： One of a plurality of voltages is adapted to be applied to power supply terminals (2a, 2b, 2c). A rectifying circuit (6) rectifies the applied voltage and develops a rectified voltage between the output terminals (6a, 6b) thereof. Inverters (16a, 16b) are connected into one of a plurality of inverter connections between the rectifier output terminals (6a, 6b) in response to one of a plurality of inverter connection indicative signals. The inverter connections are set to correspond to respective ones of the plurality of voltages, so that a predetermined voltage can be applied to each inverter whichever one of the plurality of voltages is applied to the power supply terminals. An inverter connection indicative signal generating circuit (34) is manually operated to generate a desired one of the inverter connection indicative signals. A thyristor (8) is disposed between the rectifier output terminals (6a, 6b) and the inverters (16a, 16b). When one of the plurality of voltages is applied to the power supply terminals, a voltage detecting circuit (38) generates an inverter connection indicative signal corresponding to the voltage applied to the power supply terminals. A judging unit (26d) determines whether or not the inverter connection indicative signals from the voltage detecting circuit (38) and the inverter connection indicative signal generating circuit (34) match. When the two signals match, a thyristor control unit (26a) provides a CLOSE signal to the thyristor (8). When the two signals do not match, an alarm circuit (42) is activated.

The outputs of the output-side rectifying circuits (18a, 18b) of the power supply blocks are connected in parallel with each other. The values of the reference signals generated by the reference signal generators (34a, 34b) are made always equal by the action of equipotential lines (40, 42).

摘要： DC power supply apparatus includes an input-side rectifier for converting an AC signal from an AC power supply into a DC signal. A DC-to-high-frequency converter converts the DC signal into a high frequency signal in response to a control signal from a control unit. An output-side rectifier converts the high frequency signal into a DC signal and applies it to a load. An input current detector detects an input current flowing through the input-side rectifier and generates a signal representative of the input current. A load current detector detects a load current flowing through the load and generates a signal representative of the load current. The control unit receives the input-current and load-current representative signals, a reference input current signal and a reference load current signal, and provides the DC-to-high-frequency converter with the control signal such that the input-current representative signal can be equal to the reference input current signal and the load-current representative signal can be equal to the reference load current signal.

摘要： An arc welding apparatus includes a main power supply circuit for outputting an arc current, a control circuit for controlling the main power supply circuit, and a high-frequency voltage generating circuit for generating a high-frequency voltage. When an operation switch is turned on for a first time since the apparatus is powered on, the control circuit activates the main power supply circuit to output a high voltage, and the high-frequency voltage generating circuit to generate a high-frequency voltage. With the high voltage superimposed on the high-frequency voltage, the control circuit passes a welding arc current through a torch and a base material. The switch is then turned off, and the control circuit passes a pilot arc current through the torch and the base material. The switch is turned on again, and the control circuit activates the main power supply circuit to output a high voltage, thereby allowing smooth arc transition.
