一、概述：
I. General
KST 是应用高频 PWM 脉宽调制技术，以 IGBT、场效应功率管和脉宽调制集成控制器为主要部件 而构成的开关电源式多功能充电电源。它省去了笨重又有噪音的工频变压器，使得整机重量只有可控 硅充电电源的四分之一，3KW 的 KST 充电电源整机重量 8 公斤。另外电源还提供有多个功能模块选配， 整机采用智能冷却，即使在最高温的机舱内也能保证电源可靠工作。KST 系列电源满足中国船级社的 各种规范规则，符合船用电气及规范的基本标准。 KST applies Pulse Width Modulation (PWM) technology, being multiple-function switching charging power supply with IGBT, MOSFET and PWM integrated controller as main parts. Heavy power frequency transformer with noise is not used, which makes the weight of the whole set be 1/4 of silicon controlled charger. The whole set of 3KW KST charging power supply weighs 8 kilograms. The power supply also provides several function modules for matching. The whole set adopts smart cooling process, therefore the power supply could work reliably in engine room with the highest temperature. KST series power supply meets all the specifications and rules of China Classification Society and basic standards of marine electric standards.
本充电电源为三阶段自动充电电源（恒流均衡充电-恒压均衡充 电-浮充电）如下图所示。 对电瓶充电的全过程是先进入均衡 充电，自动完成先恒流，后恒压，待电流降到接进零时均 衡充 电完成，令其自动转入“浮充”，以涓流维持电瓶在 满充状态。其充电详细过程如下： Three stages of the automatic charging power supply are constant-current equalizing charge, constant-voltage equalizing charge and floating charge as shown in the following figure. The whole process of battery charge is to enter the mode of equalizing charge first and automatically finishes the constant-current and then constant-voltage charge. The equalizing charge is finished when the current is near zero, and the mode should be transferred into “Floating charge” (manually or automatically). The trickle maintains the status of full charge. The detailed process of charge is as follows:

以 24V 铅 酸 蓄 电 池为 例 ，过 程 是：接 好 电 池，开 启 后 ，充 电 电 源 软启 动 ，电 压 从 21.6V(电 池放电下限值)开始上升，充电电流逐步增大到额定恒流值，充电电源进入恒流充电过程，此

后 充 电 电 压逐 渐 升 至 28.2V（ 均 充 电 压 值），此 恒 流 充 电过 程 一 般 情 况 下 约 需 1～2 小 时 ；然 后 ， 充 电 电 源进 入 均 衡 充 电过 程 ，在 此 过 程中 ，充 电 电 流逐 渐 缓 慢 下 降 ，电 源 退 出恒 流 工 作 ，此 时 电源电压不变，进入到恒压均衡充电状态，此充电过程约需 4～6 小时，随着电流的进一步减 小 到 额定 电 流 的 十 分之 一 时 ，电 源 自动 判 断 为 电 池已 充 好 ，电 源 自动 转 为 浮 充 阶段 ，即 输 出电 压 将 为 26.4V,充 电 电 流则 进 一 步 减 小 甚 至为 零 ，在 没 有 外部 变 化 情 况 下，此 后 电 源一 直 维 持 这 种 状 态 ，补 充 电 池的 自 耗 电 。采 用 这 种充 电 方 式 能 够较 快 、均 衡 的 对电 池 组 进 行 充电 ，充 满 后 充 电 电 源能 自 动 转 换 到浮 充 ，维 持 电 池正 常 电 压 避 免出 现 电 池 过 充 ，从 而 实 现无 人 值 守 充 电工 作方式。 Take the 24V lead acid battery as an example: the process is that when the batteries are connected and turned on, soft starting of the charging power supply is finished; voltage rises from 21.6V (lower limit of battery discharge); current increase steadily to rated value of constant current; charging power supply enters into process of constant-current charge; the charge voltage gradually rises to 28.2V (average voltage charge voltage), and the constant current charge usually lasts for 1-2 hours. Then the charging power supply enters the process of equalizing charge, and in the process the current gradually falls; the constant-current work of power supply ends. The power supply keeps being unchanged, and enters into the status of constant-voltage equalizing charge; the process lasts for 4-6 hours; as the current further falls to be 1/10 of the rated current value, the battery is automatically regarded as fully charged, and the power supply enters the stage of floating charge, i.e. the output voltage will be 26.4V and the charge current further falls to zero; then the power supply keeps the status to supply the self-consumption. The manners enable fast and equalizing charge of battery, and the charging power supply automatically switches into status of floating charge to maintain the usual voltage of battery and avoid overcharging, thus the method of charge without people’s supervision is realized. 备注：对不同种类的蓄电池其充电方式和充电压是不同的。 Notes: Charge methods and voltage of various types of battery are different.
