<p>PROBLEM TO BE SOLVED: To provide a current-detecting method which increases the accuracy of current detection, and a power supply. SOLUTION: A second current detector 21b detects a direct pulse current Ia flowing in a second transistor 25, and a direct-current Ib which flows in the reverse direction to the pulse current Ia, and does not contain ripple currents contained in the pulse current Ia, since the ripples are removed by using an electrolytic capacitor 34. The detected signal of the current detector 21b has a waveform obtained by subtracting a detected waveform of the direct current Ib from a detected waveform of the pulse current Ia.</p> |
