Explanation of key terms
According to Baidu's explanation: In daily life, there are some occasions where AC power needs to be converted into DC power, which is called a rectification circuit. In other occasions, it is necessary to convert DC power into AC power, which corresponds to the reverse process of rectification and is defined as an inverter circuit.
Under certain conditions, a set of thyristor circuits can be used as both rectifier circuits and inverter circuits. This device is called a converter, which includes rectifiers, inverters, AC converters, and DC converters.

The English name for a converter is' inverter ', which is generally implemented as a power electronic component to transfer power. It can be divided into the following types based on the voltage type before and after the conversion:
DC/DC converter, both front and rear are DC, with different voltages, serving as a DC transformer.
AC/DC converter, AC to DC conversion, the function of rectifier.
DC/AC converter, DC to AC converter, and the function of an inverter.
AC/AC inverter, with different front and rear frequencies, the function of the inverter
In addition to the main circuit (rectifier circuit, inverter circuit, AC conversion circuit, and DC conversion circuit), the inverter also requires a trigger circuit (or drive circuit) to control the on/off of power switching elements and a control circuit to regulate and control electrical energy.
The English name of the energy storage converter is Power Conversion System, abbreviated as PCS, which controls the charging and discharging process of the battery, converts AC and DC electricity, and is composed of DC/AC bidirectional converters, control units, etc.
