PURPOSE:To reduce an erroneous operation due to a noise by detecting an output voltage by a pulse width controller, comparing it with a reference value, generating a binary signal, and controlling a converter through a driver on the basis of the result. CONSTITUTION:A digital pulse width controller 13 of a power source 10 detects an output voltage V0, compares it with an inner reference voltage, and produces binary signals A1, A2 for driving a driver 12 on the basis of the result. The driver 12 receives the signals A1, A2 and produces pulses B1, B2 for directly driving a converter 11. The converter 11 generates a power pulse of a DE input V1 by the pulses B1, B2, rectifies and smoothes it and produces a stabilized DC output V0. Thus, the controller is digitized to prevent an erroneous operation due to a noise. |
