摘要： A power supply apparatus includes a front panel, a rear panel and two left and right side panels which together form a housing. Opposed edges of a partition are connected to the front and rear panels to thereby divide the interior space of the housing into upper and lower chambers. The left and right side panels each have edges which are placed to abut against the corresponding edges of the other side panel.Components of a power supply circuit are appropriately distributed in the upper and lower chambers. Some of the components in the upper chambers are located beneath the upper abutting edges of said left and right side panels, and a cover is disposed to cover at least those components which are located beneath the upper abutting edges.

摘要： A DC power supply apparatus includes a rectifier circuit for rectifying an input AC voltage to develop a rectified voltage between two output terminals thereof. First and second smoothing capacitors are connected in series between the output terminals of the rectifier circuit. First and second voltages developed across the first and second capacitors are applied to first and second inverters which convert the applied voltages to high-frequency voltages, which, in turn, are applied to a transformer. The transformer develops a transformed high-frequency voltage which is converted to a DC voltage by a converter. A voltage detector detects the first and second voltages, and the detected first and second voltages are compared in a microprocessor. An inverter control circuit controls the first and second inverters in accordance with the result of comparison, in a sense to make the voltages across the first and second smoothing capacitors equal.

摘要： An arc welder includes an inverter for converting a DC voltage to a RF voltage which, then, is rectified by a rectifier. The output of the rectifier is smoothed by a DC reactor. A RF generator provides RF current to flow between a workpiece and a main electrode of the welder forming a welder load, which initiates arcing between the workpiece and the main electrode. Initiation of arcing causes output current from the DC reactor to be supplied to the welder load, so that steady-state arcing is established. The DC reactor has a relatively small inductance which permit the output current from the DC reactor to reach a value required for establishing the steady-state arcing within a time period during which the RF generator provides RF current. The RF voltage from the inverter has a relatively high frequency so that the output current from the DC reactor can sustain the steady-state arcing.

摘要： DC power from a smoothing capacitor is converted into high frequency power by an inverter, and then lowered by an output transformer. The lowered high frequency power is converted into DC power by an output rectifier and a DC reactor, and then supplied to a load. The load is short-circuited and then opened to initiate arcing. The short-circuiting and the arcing alternate. An auxiliary rectifier provides a load-voltage representative signal, and a current detector detects a load current. A load-current representative signal is differentiated by a differentiation circuit. The signals from the auxiliary rectifier, the current detector and the differentiation circuit, and a reference signal are applied to an operational amplifier. A control circuit controls the inverter such that the output of the operational amplifier can be zero. An integration circuit receives at least the load-voltage representative signal to detect a period of a cycle consisting of the arcing and the short-circuiting and provide an operation-cycle-period representative signal to the operational amplifier.

摘要： Power supply apparatus includes a converter which converts a commercial AC voltage into a DC voltage. An inverter converts the DC voltage into a high frequency voltage. The high frequency voltage is voltage-transformed by a transformer, and then rectified and smoothed by a rectifier and a smoothing reactor into a DC voltage. This DC voltage is applied between a workpiece and a torch. A high frequency voltage generator generates a high frequency voltage and applies it to a primary winding of a coupling transformer. A boosted high frequency voltage is induced in a first secondary winding and applied between the workpiece and the torch, so that arcing is initiated. The coupling transformer includes a second secondary winding in which another high frequency voltage is induced. The high frequency voltage induced in the second secondary winding is converted into a DC voltage by a diode and a smoothing capacitor for application between the workpiece and the torch, so that the arcing is sustained.
