Abstract:
A power conversion circuit comprising a voltage estimation circuit, a current estimation circuit, and a pulse width modulation circuit. The voltage estimation circuit is configured to receive a voltage corresponding to an input of an inductor of the power conversion circuit and generate an estimate of an output voltage of the power conversion circuit based on the voltage. The current estimation circuit is configured to receive a current corresponding to a switch connected in series with the inductor and generate an estimate of an output current of the power conversion circuit based on the current. The pulse width modulation circuit is configured to produce a pulse width modulated signal based on the estimate of the output voltage and the estimate of the output current.
