    • The present invention provides a power apparatus for performing the most optimal control for overload or parasitic impedance. In order to solve the problem, a first Analog-to-Digital (A/D) converter (22) converts an analog value (S2') which is supplied to a power source terminal (P1) of a Device under Test (DUT) (1) corresponding to the analog value (S2') to a digital value (S3). A digital signal processing circuit (24) is produced by a digital operation process of a control value (S4) which is to be adjusted to match a reference value Ref to the digital value (S3). A first Digital-to-Analog (D/A) converter (26) provides an analog source signal (S1) obtained from converting a control value (S4) from digital to analog to start a power supply line (4) to the power source terminal (P1) of DUT (1). A load estimator (40) authorizes a test signal (S7) which includes some of frequency components that provides the supply line (4) to a node (N1) of which the power source terminal (P1) needs to be connected to, and it generates a control parameter (S8) of the digital signal processing circuit (24) corresponding to the test signal (S7) and the analog value of an observation signal (S2').

A quantity of charge charged/discharged during a second period is become equal to a quantity of charge charged/discharged in a capacitor during a first period. The first period is a period between a first time point and a second time point. A load current flowing into a power source terminal is changed at the first time point. The load current and the output current are matched at the second time point. The second time period is a period between the second time point and a third time point. The nonlinear controller finishes a control operation at the third time point.

    • [Task] A glitch is controlled when a resistance value of detection resistance is changed. [Task solution] A main target value setting part (10) produces a voltage target value (D_REF_V) showing a target level of power voltage (V_DD). A digital calculation part (30) produces a main control value (D_OUT) which is controlled so that a digital voltage measurement value (D_M_V), which indicates the voltage level of the current power voltage (V_DD), corresponds to the voltage target value (D_REF_V) through digital calculation processing.

    • [Task] A power signal is stabilized at a high speed when a system including load is changed. [Task solution] A power supply device (100) supplies a power signal (S_PS) to a power terminal of a device through a power line (4). An A/D converter (20) receives an analog observation value (V_M) according to the power signal (S_PS) supplied to the power terminal of the device through a feedback line (6) and converts the analog observation value into a digital observation value (D_M). A digital calculation part (30) produces a control value (D_OUT) which is controlled so that the digital observation value (D_M) from the A/D converter (20) corresponds to a predetermined reference value (Ref) with digital calculation processing. A D/A converter (40) performs digital/ analog conversion of the control value (D_OUT) and supplies an analog power signal (S_PS) to the power terminal of the device through the power line (4). A returning rate calculation part (50) calculates a ratio of the control value (D_OUT) and the digital observation value (D_M). The digital calculation part (30) is formed so that contents of calculation processing can be changed based on the ratio calculated by the returning rate calculation part (50).
