Abstract
A power converter analog chip includes a sampling circuit configured to collect electrical parameters of the power converter; a maximum power point tracking circuit configured to perform maximum power point tracking based on the input power or the output power obtained by the electrical parameters, and to obtain an adjustment signal; a rapid shutdown circuit configured to, when receiving a rapid shutdown instruction sent from the outside of the analog chip, generate a rapid shutdown signal; a protection circuit, configured to, when an electrical parameter of the power converter exceeds a first preset threshold, generate a protection signal and send the protection signal to the multiplexer; and a multiplexer configured to select one of the rapid shutdown signal, the protection signal, or the adjustment signal as a control signal, to control a power component in the power converter.
