‌InverterdeviceThe working principle of‌Mainly by utilizing semiconductor devices such as field effectspipeOr thyristorpipe）The switching characteristics of the power supply enable fast switching to control the voltage and current of the power supply, thereby converting direct current into alternating current of corresponding frequency and voltage. Inverters are widely used in fields such as solar power generation, wind power generation, household appliances, UPS, etc. ‌

The internal circuit structure of an inverter is divided into two parts: control circuit and power circuit. The control circuit mainly realizes the signal regulation and control of the inverter, including controlling the switching state of thyristors or field-effect transistors, generating high-frequency driving pulse signals, and providing protection functions. Control circuits are usually processed by microprocessorsdeviceOr composed of complex circuit boards. The power circuit is the core component of the inverter, which converts DC power into AC output, including rectification circuit, filtering circuit, etcroadAnd the inverter output circuit. The rectification circuit converts the input AC power into DC power, the filtering circuit filters and smoothes the rectified DC power, and the inverter output circuit uses semiconductor devices to convert the DC power into AC power with the required voltage, frequency, and waveform.

Full bridge inverterdeviceIt is a common inverter circuit widely used in industries, aviation, marine and other fields. The basic principle is to use four switching transistors (often IGB)TOr MOSFET）Alternating the DC power supply to achieve AC output. The control of the full bridge inverter requires precise switching control of the four switching tubes to ensure that they can switch on and off correctly in different states. In addition, filtering capacitors and inductors need to be equippeddeviceWait for auxiliary components to smooth the output waveform and reduce transient and noise interference.

PWM (Pulse Width Modulation) control is one of the main control technologies for inverters, and its basic principle is to adjust the frequency and amplitude of the output waveform by controlling the conduction time of the switching tube. PWM control is the process of converting a DC power supply into a set of short pulse signals and controlling their duty cycle to achieve high-precision AC power output.
