Abstract

The present invention is applicable to the field of electronic technology, and provides a DC / DC conversion and boosting module. The module includes an inductor, a switch tube, a diode, a capacitor, a protection unit, and a short-circuit switching device. The first pole of the input power supply is connected to the second pole of the output One pole and one end of the protection unit, the other end of the protection unit is connected to one end of the capacitor and the first pole of the switch tube; the other end of the capacitor is connected to the second pole of the output and the first pole of the diode; one end of the inductor is connected to the switch tube The second pole and the second pole of the diode, the other end of the inductor is connected to the second pole of the input power supply; the short-circuit switching device is connected in parallel with the capacitor. The DC / DC conversion and boosting module provided by the invention can solve the problems that the existing DC / DC conversion circuit may generate arc voltage and arc energy.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a DC / DC conversion and step-up module. Background technique [0002] The development of new energy and renewable energy has become the consensus of all countries in the world, and photovoltaic power generation has developed vigorously and rapidly in recent years. At present, there are two main types of photovoltaic grid-connected power generation schemes: [0003] Option 1: Centralized high-power photovoltaic grid connection. Multiple PV modules are connected in series and sent to the combiner box as a branch. The combiner box is generally 8, 12 and 16 channels. Many PV strings are combined by multiple combiner boxes, and then output to the DC input port of the inverter through the shunt switch of the DC power distribution cabinet, and then input to the DC circuit breaker switch of the inverter for DC / AC inversion and parallelization. network. [0004] Scheme 2...
