| 摘要 |
<p>The invention relates to a battery discharger comprising a controlled switch (46) which is conductive for discharging a battery when the voltage of this battery is greater than a first reference voltage (Vr1). The controlled switch is periodically opened and closed due to the fact that the voltage representing the battery voltage which is used to control the switch, has a greater value when the switch is "off" than when the switch is "on". At least a circuit element (44) is provided in order to extend the on period of the switch (46) when the voltage representing the voltage battery is higher than the first reference voltage (Vr1). <IMAGE></p> |
