ABSTRACT:
A non-isolated boost converter with input and output current steering. The input current steering is connected across the input switching transistor, is magnetically coupled to the input inductor and conducts the input current when the switch is turned off, thereby reducing ripple in the input current. The output current steering is connected across the diode in the low-pass output filter and is magnetically coupled to the input inductor to generate an induced current for the output filter when the switch is turned on, thereby preventing the output current from pulsating. With the output filter connected across the switch, a boost converter is formed with the output dc voltage being greater than the input dc voltage in relation to the switching duty cycle. With the output filter connected across the input inductor, a buck-boost converter is formed with the output dc voltage being greater than or less than the input dc voltage in relation to the switching duty cycle.
