摘要： PROBLEM TO BE SOLVED: To provide a loading device which is capable of accurately monitoring a load current flowing in a power source while reducing the instability of control of the load current due to an inductance component of electrical connection means (a cable or the like) to the power source.SOLUTION: Connection of a CR circuit 10 between input terminals TP1 and TP2 makes it difficult that current at a high frequency due to resonance or the like caused by inductance components of load cables LN1 and LN2 flows to a transistor Q1, so that feedback control of a current control unit 30 can be prevented from being unstable. A current Id1 of the transistor Q1 is detected in a shunt resistance Rs1, and a current Id2 of the CR circuit 10 is detected in a shunt resistance Rs2, and these detection signals are combined to generate a detection signal V2 of a load current Id, so that a transiently changing waveform of the load current Id can be correctly observed.

摘要： PROBLEM TO BE SOLVED: To obtain an AC power supply device that can feed a large-power and high-quality AC voltage waveform by a single constitution that does not need parallel synchronous operations of a plurality of devices. SOLUTION: An AC voltage output generated by an inverter circuit that can feed only small power at a low-withstand voltage but which can perform high-speed switching is connected in series to an AC voltage output that can feed large power at a high-withstand voltage but which causes the distortion of an AC voltage waveform in low-speed switching. A low-speed switching inverter circuit is feedback-controlled by the output voltage of the circuit, and a high-speed inverter circuit is negative-feedback controlled to generate an AC voltage in a voltage range, wherein an AC voltage waveform distortion component such as ripple noise included in the AC voltage output of the low-speed switching inverter circuit is compensated, thus constituting a circuit system. The circuit system enables large-power and high-quality AC voltage output to be obtained by using a single device. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a loading device capable of testing loadings with large instantaneous peak, while constraining jumboizing of device size.
SOLUTION: When a condition of loading occurs where the temperature of loading section 2 rises above a rated temperature, upper limit preset signals L1 and L2 are generated so as to lower the upper limit of load electric power according to temperature rise of the loading section 2, and thus the load current is restricted according to these upper bound preset signals L1 and L2. Thereby, even when large instantaneous load is driven, temperature rise of the loading section 2 is controlled to prevent arriving at a rated temperature.

摘要： PROBLEM TO BE SOLVED: To provide a loading device for suppressing heat loss by power conversion of load power through a switching operation, and reducing ripple of load current accompanying with the switching operation.
SOLUTION: In a power conversion unit 10, input current I1 is controlled so as to be close to a first target value, and electric power input from load nodes N1 and N2 is converted into ac power and regenerated in an AC system 40. At this time, ripple of the input current I1 generated accompanying with a switching operation of the power conversion unit 10 is smoothed by correction current I2 of a correction current generating unit 20. Therefore, heat loss is drastically suppressed and ripple of load current IL is effectively reduced which accompanies with the switching operation of the power conversion unit 10 compared to conventional systems in which total load electric power is consumed by a transistor and the like.
