Applications
IIT Madras
RESEARCH FUNDED BY INDIAN SPACE RESEARCH ORGANISATION (ISRO)
• High Voltage DC-DC Converters with programmable output voltage are required for low power capacitor charging and discharging
applications in equipments like defibrillator, piezoelectric and dielectric actuators, ion analyzer, etc. Such converters often need to
be powered from a low voltage battery powered supply.
• Low component count makes bidirectional flyback converter a preferred topology for such applications. Performance of such con-
verters is affected by the presence of device parasitic capacitance. A variable frequency based hardware sensed resonance valley
switching technique is used to exploit the presence of parasitic capacitance for soft switching.
• An energy based approach is used to provide a simplified mathematical description for the voltage built up process with respect to
number of charging cycles. An ON-OFF based control scheme is derived based on the model to achieve a programmable output by
modulation of energy per cycle.
• Experimental validation of the work is presented with a hardware setup for 0V to 3kV programmable high voltage output from 12V
input supply.
