working principle of dc dc resonant converter

INTRODUCTION
In recent years, is quickly becoming the technology
Innovation, Suŝestvuetthere increasing demand for reduced size,
weight and cost. This is the working of the resonant DC-DC boost
The converter operates at very high frequency range
MHz and is controlled by the MPPT controller. This converter has
A few Advantages are another common
converters call them
 the main advantage of reduced weight, size and cost
What is required in the present day of power electronics.
 the resonant boost topology combined with zero
switching voltage switching losses will significantly

 The work at very low energy storage requirements for VHF
