Technical FAQs 4

What is a ZVS based inverter?

A ZVS-based Royer oscillator or Class-D inverter ensures soft switching, preventing thermal stress on IGBTs or MOSFETs. The load impedance (Zload) is matched to the inverter output using a resonant tank, enabling ZVS over a wide range of operating conditions.

What is a zero voltage switching (ZVS) inverter?

It is developing a Zero Voltage Switching (ZVS) inverter. What does this mean, and why does it matter? Inverters convert DC power to AC power via pulse width modulation, which is covered in our primer into electricity.

Does Hillcrest's ZVS inverter reduce switching losses?

Our Hillcrest technology review evaluates the company's ultra-efficient ZVS inverter which is targeting 30-70% lower switching losses.

Why is ZVS important in power electronics?

ZVS is important in power electronics because it reduces switching losses, improves energy efficiency, and minimizes heat generation in switching circuits. It also helps to reduce electromagnetic interference (EMI) and noise. How does ZVS achieve zero voltage across the switching device?
