A high-voltage full bridge inverter works by converting the DC voltage V1 to a high-frequency square wave AC voltage. This AC voltage is then supplied to a 20kHz frequency high-voltage transformer T1, which, after the boost rectifier, provides power to the load. The inverter high-voltage full bridge drives the routing components and the IGBT power modules.
The main circuit of an inverter includes an inverter DC power supply, IGBT bridge inverter, protection circuits, high frequency high voltage transformers, and high frequency high voltage silicon stack (Rectifier).
Typically, they are on the high voltage side (from 30 kV to 150 kV and more), and are made by connecting back-to-back controlled rectifier and inverter employing a DC bus. Dealing with high voltages, classical bridge rectifiers, and two-level inverters are not suitable due to the limited characteristics of electronic switches.
The higher voltage supplies large loads such as traction motor, air-conditioning, and starters. Lower-power components such as infotainment and safety systems will remain on 12V supplies. What does this EE do? PMP7797 is a wide-input SEPIC converter designed for automotive applications.
Considering the high power levels and voltage levels, a three-phase inverter uses six isolated gate drivers, as shown in Figure 2. Each phase uses a high- and low-side IGBT switch, usually operating in the 5kHz to 20kHz range, to apply positive and negative high-voltage DC pulses to the motor windings in an alternating mode.
PWM technology is widely applied in high-voltage power supply inverting and inverse frequency fields. The development of IGBT, MOSFET, and other power switching devices for PWM control of high-voltage power supply is moving towards miniaturization, high frequency, and intelligence. Along with this, the trend is towards higher efficiency.
