Hi, in this video I'll show you how to make a Pure Sine Wave Inverter without any IC. Its based on a ZVS Driver (Zero Voltage Switching). An LC tank oscillates at its resonant Frequency with a Pure Sine Wave across it. The high frequency Transformer then steps up the voltage.
Zero Voltage Switching (ZVS) Full Bridge Driver:
Background:
ZVS is a technique used in power electronics to minimize switching losses in power converters. The Full Bridge topology is a common circuit configuration used in power electronics, and ZVS is often implemented in the driver circuit to optimize its performance.
Working Principle:
Switching Strategy:
The ZVS Full Bridge Driver aims to turn on or off the power switches (usually MOSFETs or IGBTs) when the voltage across them is close to zero. This reduces switching losses and enhances overall efficiency.
Phase Shift Control:
Typically, ZVS Full Bridge converters use phase-shift control. This means that the switches are controlled in such a way that they are turned on and off at specific phases of the input voltage waveform, ensuring that the voltage across them is minimal during the switching transitions.
Soft Switching:
By achieving ZVS, the switching transitions become "soft," meaning that the switches turn on or off when the voltage or current is at or near zero. This minimizes the generation of switching losses, reducing stress on the components and improving overall efficiency.
Advantages:
- Reduced switching losses lead to higher efficiency.
- Lower stress on components, which can result in increased reliability.
- Improved performance in high-frequency applications.
Applications:
ZVS Full Bridge Drivers are commonly used in high-frequency power converters, such as induction heating systems, switch-mode power supplies, and some types of resonant converters.
