High frequency bi-directional dc-dc converters are currently widely used in a diversity of
power electronic applications. In order to interconnect the various DC sources at different
voltage levels, one requires bi-directional DC/DC converters capable of converting the
voltage from one level to another whilst also able to control the direction of power flow
through the converter. The use of a bi-directional dc-dc converter in motor drives devoted
to Electric Vehicles (EV) allows a suitable control of both motoring and regenerative
braking operations. A bi-directional arrangement of the converter is needed for the reversal
of the power flow, in order to recover the vehicle kinetic energy in the battery by means of
motor drive regenerative braking operations.
A full-bridge, single phase inverter and converter that uses Pulse Width Modulation (PWM)
to control the power switches was constructed. The concept of PWM with different
strategies for converter is described. The PWM was produced with a simple circuit and
using several chips and devices that are easily available in the market. The PWM signals
are simulated using OrCAD simulation tools. MOSFET IRF520 is used for high frequency
switching in both sides inverter and converter. An isolation transformer (ratio 1:1) is used
between inverter outputs and input of bi-directional of DC-DC converter.
The proposed converter has the advantages of high switching frequency, high efficiency,
simple circuit, low cost and bi-directional power flow. The detailed design and operating
principles are analyzed and described. The simulation and experimental waveforms for the
proposed converter are shown to verify its feasibility. |
