The SG3525-based H-bridge inverter circuit is a reliable and efficient solution for converting DC voltage to AC power. With features such as voltage regulation and low battery protection, it is suitable for powering a wide range of devices.
The simplest form of an inverter is the bridge-type, where a power bridge is controlled according to the sinusoidal pulse-width modulation (SPWM) principle and the resulting SPWM wave is filtered to produce the alternating output voltage. In many applications, it is important for an inverter to be lightweight and of a relatively small size.
The SG3525-based H-Bridge inverter circuit converts low-voltage DC into high-voltage AC, making it ideal for use in applications like renewable energy systems, backup power supplies, and portable inverters. Below is a detailed description of the circuit components and their roles. You can also see block diagram of SPWM inverter circuit.
In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
H-Bridge MOSFET Power Stage The H-bridge stage consists of four N-channel MOSFETs (e.g., IRFZ44N), which switch the DC voltage across the transformer’s primary winding to generate an alternating waveform. Gate Resistors: Resistors are connected to the MOSFET gates to limit the gate charging current and prevent ringing.
Below is an overview of the primary elements: SG3525 IC: The main controller for generating PWM signals to drive the MOSFETs in the H-bridge configuration. H-Bridge MOSFETs: Power transistors (typically N-channel MOSFETs such as IRFZ44N or IRF3205) that switch the DC voltage to generate an alternating waveform.
