This paper proposes a multioutput hybrid bipolar converter (MOHBC) and a different operational approach for achieving maximum power point tracking (MPPT) operation for photovoltaic systems. The proposed MOHBC simultaneously provides bipolar DC (inverted and non-inverted) and AC outputs and is designed by the integration of Cuk and SEPIC converters with some circuit modifications. For the proposed MOHBC, two control parameters; the duty ratio d and the modulation index $m_{\mathrm{a}}$ are used to control the bipolar DC and AC output, respectively. The MPPT operation is achieved by controlling d and $m_{\mathrm{a}}$ in four different operating modes of the proposed MOHBC. The steady-state and transient response of the proposed MOHBC during the MPPT operation in four different modes are verified using PSIM. Finally, a comparative analysis of MPPT operation in the different modes is carried out in this work.
