The invention discloses a digitalized-control low-
voltage direct-current power source
energy feedback type electronic loading boosting
system comprising a main circuit and a
control circuit. The main circuit comprises a Boost module and a DC (
direct current)-DC boosting conversion module which are sequentially connected, the Boost module is connected with a parallel low-
voltage direct-current power source, and the DC-DC boosting conversion module is connected with a grid-connected
inverter system. The
control circuit comprises a fault protection circuit module, a current and
voltage sampling and
signal processing module, a DSP (
digital signal processor) embedded
type system module and a high-frequency driving module. The digitalized-control low-voltage direct-current power source
energy feedback type electronic loading boosting
system thoroughly solves the problems that
energy feedback is hard to realize during
ageing of the low-voltage direct-current power source and a conventional
static loading is energy-consuming, heating and large in size, and is energy-saving, efficient, environment-friendly, reliable in performance, high in
automation degree and stable in power source
ageing quality, and is particularly applicable to reliability test, on-load test and output characteristic test of the low-voltage direct-current power source.
