Interests in resonant converters arose from the quest for utilizing very high switching frequencies without unacceptable power dissipation in the semiconductor switches. Switching losses can be minimized using resonant system and also very high operating frequency can be employed allowing smaller and lighter power-conditioning equipments to be built. In addition, power density and efficiency of the power conditioning can be increased while reducing the EMI problems. Two closed loops are designed here, first one is speed control loop which regulates the speed of the dc motor so that motor rotates in accordance with the reference speed signal and other is the current control loop which controls the input current to the motor. Switching pulses to the switch is generated by microcontroller. Switching frequency is to be varied so as to vary the output of the resonant converter, therefore it is known as frequency modulated converter.
