Electric power converter including a stabilization circuit

An electric power converter configured to convert DC power to AC power, comprising:

• a DC stabilization circuit configured to stabilize a DC voltage from DC power supply;
• and
• an inverter configured to convert the DC voltage stabilized by said DC stabilization circuit to an AC voltage,
• said DC stabilization circuit including:
• first and second input terminals configured to receive the DC voltage from said DC power supply;
• first and second output terminals connected to said inverter;
• a smoothing capacitor connected between said first and second input terminals and configured to smooth the DC voltage between said first and second input terminals;
• a saturable reactor connected between said first and second input terminals and said first and second DC output terminals, and configured to prevent said DC stabilization circuit from oscillating;
• and
• a film capacitor connected between said first and second DC output terminals and configured to supply a ripple current to said inverter, wherein
• said saturable reactor includes a first coil connected between said first DC output terminal and said first input terminal and a second coil connected between said second input terminal and said second DC output terminal, and
• said first and second coils are mutually magnetically coupled.
