How a Car Inverter Works
Step 1: DC-DC Conversion
When the car is turned on, the DC-DC converter takes the DC power from the battery and converts it to a higher voltage, typically between 12V to 24V. This higher voltage is then fed to the inverter stage.
The DC-DC converter uses a switching circuit to regulate the output voltage and prevent overvoltage or undervoltage conditions. The switching circuit consists of a power switch, a controller, and a feedback circuit. The power switch is typically a high-power transistor or a power MOSFET, which is controlled by the controller. The feedback circuit monitors the output voltage and sends a signal to the controller to adjust the switching frequency and duty cycle to maintain the desired output voltage.
Step 2: Inverter Conversion
The inverter stage takes the higher voltage from the DC-DC converter and converts it to AC power using a switch-mode topology. The inverter stage consists of a switching circuit, a transformer, and a filter circuit.
The switching circuit uses a high-power transistor or a power MOSFET to switch the DC power on and off at a high frequency, typically between 10kHz to 100kHz. The switching circuit is controlled by a controller, which adjusts the switching frequency and duty cycle to maintain the desired output voltage and waveform.
Step 3: Filter Circuit
The filter circuit takes the AC power from the inverter stage and filters out the EMI and other unwanted signals. The filter circuit consists of a capacitor, an inductor, and a resistor.
The capacitor filters out the high-frequency components of the AC power, while the inductor filters out the low-frequency components. The resistor filters out the DC component of the AC power.
