Comparison of Isolated dc/dc converters.

Type	DC-DC converter	Objective	Outcomes	Benefits	Drawbacks
ISOLATED CONVERTER	Fly-back converter [[101], [102], [103]]	To accept a wide variety of input voltages	Reduces leakage inductance to an appropriate level.	performance is separated from the primary. Multiple output voltages are possible. Ability to control multiple output voltages.	Ripple current. Losses are higher. More capacitance at the output and input. In the compensation loop is the right half pole.
	Push-pull converter [108,109]	To adjust the DC power supply’s voltage	starting power is limited. On the main line, it achieves low current and voltage.	Transistors and transformers are used more efficiently. EMI is reduced. Filtering isn’t as necessary.	Transformer for the central tap. In the flux walking phenomenon, two switches are rarely used.
	Zero voltage switched capacitor [[111], [112], [113]]	To provide enough power over a wide variety of load variations. To achieve an adequate level of soft-switching reliability. The output diode bridge voltage is clamped.	In all load conditions, achieves zero voltage switching. The symmetric auxiliary circuits ensure a safe and efficient operation under no-load conditions.	EMI is poor. Switching losses is low. There is no need for an additional clamping circuit.	It is necessary to use a large capacitor. Current ratings are High. Fault-tolerance is lacking.
	Resonant converter [[118], [119], [120]]	To minimize magnetic components and passive filters	Achieves a high level of step up/step down capability. Achieves a high level of quality. Offers a broad range of voltage gain	Low cost. Conversion rate is very high. High productivity.	Expensive controller. Complex integrated transformer.
	Multiport Isolated dc-dc converter [125,126]	Optimizing the system’s efficiency by controlling the duty cycle. To reduce overall device losses as much as possible. To look at the complex analysis and the control strategy that goes with it.	Achieves a dynamic response is fast. Power flow can be regulated independently. High efficiency is achieved by duty cycle and phase shift management.	Voltage gain is high. Low ripple current in the output voltage. Isolation by galvanic action.	Under steady-state and intermittent conditions, complex analysis is performed. The duty cycle under load shifts leads to high sensitivity. Synchronization is difficult to obtain.
