| titleOfInvention | Solar street lamp controller topology circuit |
| abstract | The utility model discloses a solar street lamp controller topology circuit. A LED lamp is connected in series with a fifth field effect transistor and then is connected between a positive input terminal and a negative input terminal of a bidirectional DCDC converter. A solar photovoltaic plate is connected in series with a first field effect transistor and then is connected between the positive input terminal and the negative input terminal of the bidirectional DCDC converter. A storage battery is connected in series with a fourth field effect transistor and then is connected between a positive output terminal and a negative output terminal of the bidirectional DCDC converter. The negative input terminal of the DCDC converter is grounded. A driving circuit is connected to grid electrodes of the first, fourth and fifth field effect transistors. The topology circuit of the utility model fully uses a characteristic that charging and discharging of a solar street lamp system are performed at different times. During a charging process, the bidirectional DCDC converter is a buck converter; during a discharging process, the bidirectional DCDC converter is a boost converter. A utilization rate of a power device is doubled. Manufacturing cost is reduced. The size is decreased and engineering installation is convenient. |
