Charger
Electric bicycle charger is a charging device specially configured for the electric bicycle battery, commonly used switching power supply chargers are divided into two categories: half-bridge and single-excited, and single-excited is divided into two categories: forward-excited and flyback. The half-bridge type has high cost and good performance, and is commonly used in chargers with negative pulse; the single-excited type has low cost and high market share, and most of the chargers in the current market are flyback type.
