Is a resonant converter hard or soft switching?
Resonant converters are soft switching; therefore, if the voltage across the switch is zero when it is turned on, it is ZVS. The switch will be referred to as ZCS if the current that flows across it is zero while it is in the OFF position. Figure 3 shows a switch’s hard and soft-switching characteristics.
How does a boost switch control the output of an inverter?
The two load voltages of the converter are controlled by two different modulation techniques. As boost circuit is integrated with the first leg of the inverter circuit, duty cycle of the boost switch is constant for independent operation. Hence, frequency control is applied to control the output.
How to control the output of a boost switch?
As boost circuit is integrated with the first leg of the inverter circuit, duty cycle of the boost switch is constant for independent operation. Hence, frequency control is applied to control the output. The second output is controlled by the duty ratio control. Schematic diagram showing the open-loop control of converter is in Fig. 14.
