Resonant mode conversion techniques are used nowadays to improve pulse width modulated dcdc converters. Moreover the quest for ever smaller 50 to 500 watts dc-dc switching supplies has led to the development of circuits that operates in 500 KHz -1 MHz range and above. Since the parasitic elements that normally present in a power circuit can be very significant at this frequency, most of the wor...
