Zero Voltage Switching (ZVS) has been around for decades, but with limitations.
Now there is a better, more efficient solution:
Predictive Lossless SwitchingTM
Why we developed PLSTM
1980’s power control limits the drive to smaller, more efficient and lower cost products.
Traditionally, increasing switching speed has been used to reduce size and lower cost, but this is limited by efficiency losses and control logic complexity.
Current Industry Practices
Zero Voltage Switching Limitations:
- Static control over timing of switching devices (such as deadtimes) limits operation to narrow load bands.
- Heavily affected by variances in input voltage, parasitic capacitants, overvoltage ranges and inductor tolerances.
The Indice Solution
- Higher efficiency
- Higher potential switching speed: 10x or greater
- Works over a broad range of frequencies and duty cycles
- Smaller components: surrounding passive components can be smaller
- Works with all switching devices (IGBT, Si, SiC, GaN)
