A two-stage microinverter for coupling a PV panel to a power grid includes a DC/DC converter stage having an input for coupling to the PV panel and a DC/AC inverter stage that has an output for coupling to the grid, with at least one DC link capacitor between the DC/DC converter and DC/AC inverter stage. A synchronous controller that includes a loop compensator coupled to a mixer is between an analog-to-digital converter (ADC) and a phase-locked loop (PLL) for coupling to an output voltage from the grid. The ADC receives a DC link voltage from the DC link capacitor. An output of the PLL is for controlling a timing of sampling by the ADC of the DC link voltage so that the ADC samples the DC link voltage when an AC component of a ripple voltage on the DC link voltage intersects an average value of the DC link voltage.
