Principle of temperature compensation charger
Source:
The electric bicycle charger with temperature compensation function includes the basic circuits of rectifier filter, high-voltage switch, voltage conversion and constant current and constant voltage charging controller. Its characteristics are: it also includes temperature compensator circuit, which is mainly composed of temperature sensor D↓[T], inverting differential amplifier A↓[1], inverting differential amplifier A↓[2] and its bridge circuit, the temperature compensator is connected between the voltage converter of the basic circuit and the constant current and constant voltage charging controller, and is integrated into the voltage negative feedback loop of the whole circuit structure with the output voltage of the basic circuit amplifier.
