WORKING PRINCIPLE OF INVERTERS
- The direct current is smoothed and filtered by a filter circuit.
- The inverter uses semiconductor devices as switching components to adjust the voltage, frequency and waveform of the output alternating current by controlling the switching state and frequency.
- Pulse width modulation (PWM) technology controls the on-time of the switching element so that the output AC is close to the desired waveform (such as a pure sinusoidal waveform).
- The output AC passes through the output filter circuit for further filtering and noise removal.
- The control circuit includes protection functions such as overload, short circuit and overheat protection to ensure the safety of the inverter and equipment.

What Are The Common Functions Of Inverters?
Pure Sine Wave Inverter (Pure Sine Wave Inverter) : This inverter is capable of producing a near-perfect sinusoidal waveform output, suitable for high power quality applications, such as precision electronics and sensitive motor drives.
Modified Sine Wave Inverter (Modified Sine Wave Inverter) : This inverter output waveform is approximated in some way, the waveform is not as smooth as pure sine wave, but is suitable for the use of most common electrical appliances.
Square Wave Inverter (Square Wave Inverter) : This inverter output waveform is square wave, often used in some low-power, simple applications, such as lighting and power tools.
Pulse Width Modulation Inverter: This inverter uses pulse width modulation technology to control the shape and amplitude of the output waveform by adjusting the on-time of the switching element. It can produce an output close to a pure sine wave, while having high efficiency.
Difference Between Power Frequency Inverter And High Frequency Inverter
Power Frequency Inverter: Power frequency inverters convert DC power to AC power, matching the input grid frequency (typically 50Hz or 60Hz). They are commonly used in power systems to meet industrial and residential electricity requirements.
High-Frequency Inverter: High-frequency inverters convert DC power to high-frequency AC power, achieving a higher output frequency than the input power frequency. They utilize a transformer to convert the high-frequency AC power to the desired output voltage. High-frequency inverters offer advantages such as increased power density and efficiency due to higher switching frequencies. They find applications in electronic devices, solar power systems, electric vehicles, and UPS.

Difference Between Off-Grid Inverters And Grid-Connected Inverters
Connected to The Grid: off-grid inverters are used for independent off-grid systems, not connected to the main grid. Grid-connected inverters are used to connect the energy of renewable energy systems (such as solar photovoltaic systems) to the main grid, and can inject excess energy into the grid or obtain electricity from the grid
System Design Purpose: Off-grid inverters are designed to provide an independent power system that does not depend on the main grid for power supply. Grid-connected inverters are designed to connect renewable energy systems to the main grid so that electrical energy can be interconnected and shared
Control Strategy:Off-grid inverters control energy output based on battery voltage and load demands for stable off-grid system operation. Grid-tied inverters adhere to electrical grid requirements, monitoring and adjusting parameters like voltage, frequency, and power factor for coordinated operation.
Safety Requirements: Grid-connected inverters meet grid safety standards for stable and secure grid connection. Off-grid inverters prioritize battery management and self-sufficiency for reliable off-grid power supply.
