    摘要: A small-sized DC power supply apparatus adapted for receiving input commercial AC voltages of different value includes an AC-to-DC converter 4 which converts an input commercial AC voltage to a first DC voltage. The first DC voltage is converted to a high-frequency voltage in an inverter 10 including IGBTs 10a-10d which are rendered conductive when a conduction control signal is applied thereto. A transformer 12 transforms the high-frequency voltage, which is, then, converted to a second DC voltage in a high-frequency-to-DC converter 16 for application to a load 22. The conduction control signal with a pause period disposed therein is generated in a controller 14. The conduction control signal occurs at a fixed period. The pause period disposed between the successive occurrences of the conduction control signal becomes longer as the input commercial AC voltage is higher.

    摘要: An input rectifier of a power supply apparatus rectifies a selected one of two, higher and lower AC voltages applied to it. First and second inverters are connected in the output of the input rectifier. A high-frequency transformer is connected to the output of each of the first and second inverters. An output rectifier is connected to the output of each of the high-frequency transformers. When the higher one of the two AC input voltages is applied to the input rectifier, a switching circuit connects the first and second inverters in series between output terminals of the input rectifier. When the lower AC voltage is applied to the input rectifier, the switching circuit connects the first and second inverters in parallel between the output terminals of the input rectifier. When the first and second inverters are connected in series between the output terminals of the input rectifier, a voltage balancing control unit operates to suppress imbalance between input voltages to the first and second inverters.

    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.

    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.
