Inverters derived from voltage source (VSI) are ideally suited for supplying power to a resistive and inductive load and the applications that require constant torque operation of AC motors. Current Source Inverters (CSI) are ideally suited for supplying power to largely capacitive loads and AC voltage buses. Inverters can be further classified on the basis of the mode of control of the output variable: voltage or current.

电压源型变频器特别适合于对于要求恒转矩运行的感性负载或者阻性负载电机。电流源变频器特别适合大容量负载和交流供电母排。变频器按输出的基本控制方式分为电压型和电流型。 Inverter control in practice concerns three aspects: fundamental frequency, amplitude, harmonic profile.

Fundamental frequency is either equal to the switching frequency of the inverter (square-wave and PWM inverters) or its simple fraction (1/3, 1/5, and so on) such as in Multiple PWM or sine PWM inverters

实际上变频器的控制关心3个方面：基础频率，频率的幅值，谐波情况。基础频率等于变频器的开关频率，或者是开关频率的分数（三分之一，五分之一等），像是在多重脉宽调制变频器或者正弦脉宽调制变频器。Power electronic applications require the amplitude control of output voltage or output current, called Voltage-Mode control and Current-Mode control respectively. An example of Voltage-Mode control is the adjustable speed drives of induction and synchronous motors. An example of Current-Modecontrol is a constant torque drive for induction motors. Output amplitude in both modes can be controlled by varying the DC source voltage or by varying the pulse-width (pulse-width modulation, PWM).电力电子装置要求对于输出电压和电流的幅值进行调节，分别叫做电压控制型和电流控制型。电压控制型的例子是同步机和感应电机的调速装置（变频器），电流型控制器应用在恒转矩感应电机。输出幅值在两种控制方法以调节直流源电压或者是调节脉冲宽度实现（简称PWM）。The inverters based on the control of DC source voltage are also termed DC-Link Inverters. These inverters use an AC to controlled DC converter on the input side. The inverter is square-wave controlled. This arrangement is expensive but exhibits a faster response time than PWM inverters. The control circuitry is also simpler. Harmonic profiling is an extra feature added over the amplitude control. 基于控制直流源电压的变频器也被叫做有直流环节的变频器。这些变频器用交流控制在输入侧的直流。使用方波调制的变频器要贵于采用PWM控制方式的变频器，电路也更小。谐波概况在幅值控制是另一个特性。The objective of harmonic profiling is to bolster the amplitude of the fundamental component of the output voltage and the elimination or reduction of high order harmonics. One of the techniques involves the notching or adding step pulses to a base pulse. The other technique involves multiple pulses per cycle of the fundamental, each pulse-width modulated to achieve desired wave-shaping of the output waveform (Sine-PWM).

能不能给加点分啊。

储能系统认证—功能安全标准简介

储能系统认证—功能安全标准简介

功能安全是通过系统评估确保每个主动式保护元件在潜在的随机性失效风险下都能维持正常运行，以保障整个系统的安全，包括类似操作员失误、硬件失效、环境变化等的安全管理。在储能系统中，功能安全尤为重要，因为储能电池在异常工作状态及极端的工作环境下容易引发起火、漏液甚至爆炸等灾难性事故。因此，企业需要考虑储能电池安全控制系统可靠性设计，通过安全设计及试验论证，确保电芯或保护板在常规失效发生后避免引发严重的灾难性事故。
