摘要： A battery charger for rapidly charging batteries of different capacity types is controlled by a microprocessor. The microprocessor controller is also connected to a voltage source which is connected to the battery for supplying a charging current to the battery at a current value selected by a user. The controller is also connected to a voltage reference generator which generates a reference voltage equal to a conditioned battery voltage at the beginning of a charging cycle. The reference voltage increases in predetermined voltage increments as the battery voltage increases during the charging cycle until the battery voltage reaches a peak voltage. A comparator compares the conditioned battery voltage to the reference voltage and sends the results of the comparison to the microprocessor controller. The microprocessor controller causes the reference voltage generator to increase the reference voltage by a predetermined voltage increment if the conditioned battery voltage is greater than the reference voltage. If the conditioned battery voltage is less than the reference voltage for a first predetermined time period, the microprocessor causes the voltage source to decrease the charging current to a trickle charge.
摘要翻译：用于快速充电不同容量电池的电池充电器由微处理器控制。微处理器控制器还连接到电压源，该电压源连接到电池，用于以由用户选择的当前值向电池提供充电电流。控制器还连接到电压参考发生器，其在充电周期开始时产生等于调节电池电压的参考电压。随着电池电压在充电循环期间增加，直到电池电压达到峰值电压，参考电压以预定的电压增量增加。比较器将调节的电池电压与参考电压进行比较，并将比较结果发送到微处理器控制器。如果调节的电池电压大于参考电压，则微处理器控制器使参考电压发生器将参考电压增加预定的电压增量。如果调节电池电压在第一预定时间段内小于参考电压，则微处理器使电压源将充电电流减小到涓流充电。

摘要： A full wave rectifier regulator for an alternator battery charging system has gate controlled rectifier connected in two separate branches of the rectifier bridge. The gates of the rectifiers are connected to the anode-cathode circuit of a third gate controlled rectifier (SCR) and are thereby selectively turned "on" and "off" by the current flow in the anode-cathode path of the SCR. A portion of the alternator output voltage triggers the SCR to its conductive mode whenever the battery voltage is between predetermined voltage levels. A protection circuit comprising an electronic switching component is connected to the gate of the SCR to shunt off any gate triggering current to hold the SCR "off". The switching component is connected to sense the battery voltage and to clamp "off" the SCR should its voltage either be lower or higher than the predetermined levels. The regulator further includes means for shorting the output of the rectifier to its input terminals at a voltage substantially higher than the normal operating voltage levels of the system. A storage capacitor is also included to hold said SCR "off" for a predetermined time to prevent rapid cycling of the system about an abnormally high output voltage.

摘要： A single or multiphase boost chopper regulator operating with unity power factor, for use such as to charge a battery is comprised of a power section for converting single or multiphase line energy into recharge energy including a rectifier (10), one inductor (L.sub.1) and one chopper (Q.sub.1) for each chopper phase for presenting a load (battery) with a current output, and duty cycle control means (16) for each chopper to control the average inductor current over each period of the chopper, and a sensing and control section including means (20) for sensing at least one load parameter, means (22) for producing a current command signal as a function of said parameter, means (26) for producing a feedback signal as a function of said current command signal and the average rectifier voltage output over each period of the chopper, means (28) for sensing current through said inductor, means (18) for comparing said feedback signal with said sensed current to produce, in response to a difference, a control signal applied to the duty cycle control means, whereby the average inductor current is proportionate to the average rectifier voltage output over each period of the chopper, and instantaneous line current is thereby maintained proportionate to the instantaneous line voltage, thus achieving a unity power factor. The boost chopper is comprised of a plurality of converters connected in parallel and operated in staggered phase. For optimal harmonic suppression, the duty cycles of the switching converters are evenly spaced, and by negative coupling between pairs 180.degree. out-of-phase, peak currents through the switches can be reduced while reducing the inductor size and mass.
