| Abstract: | A switching mode power supply scheme is put forward based on PWM integrated chip of electric current mode SG3525. This scheme is applied to brushless direct current motor controlling module in the solar electrical bicycle. This design adopts half-bridge mode converter as the main circuit, and includes over-current detection and output sampling feedback. It can well satisfy the power supply demand for the controlling module, due to its quick response, excellent stability and precise voltage output. |
