Power converter and image processing apparatus

An image processing apparatus, comprising:

• a printing unit configured to print an image on a sheet;
• and
• a power converter configured to convert an AC voltage to a DC voltage and output the DC voltage to the printing unit, the power converter including:
• a first circuit including an inductor and configured to convert an input AC voltage into a first DC voltage and output the first DC voltage,
• a second circuit including a transformer and configured to convert the first DC voltage to a second DC voltage and output the second DC voltage,
• a first control circuit configured to control the first circuit,
• a first power supply circuit including a first winding magnetically coupled to the inductor and configured to output a third DC voltage generated by the first winding to the first control circuit, and
• a second power supply circuit including a second winding magnetically coupled to the transformer and configured to output a fourth DC voltage generated by the second winding to the first control circuit, wherein
• during output of the first DC voltage from the first circuit, the third DC voltage is output from the first power supply circuit to the first control circuit when the second DC voltage is not output from the second circuit, and the fourth DC voltage is output from the second power supply circuit to the first control circuit when the second DC voltage is output from the second circuit.
