Peak Current Mode Control

A boost power factor correction (PFC) in continuous conduction mode (CCM) by the digital peak current-mode control method with bifurcation control is discussed in this paper. The proposed method is used to prevent the inductor current bifurcation behavior, which is caused by sub-harmonic oscillation when the duty cycle is upon to 50 percent. The bifurcation behavior will increase the inductor current ripple and dissipation, then reduce the Power Factor (PF). Different from the ramp compensation signal performed with analog IC in some papers, a MCU is used to be the controller and also provides the digital compensation function in this paper. With the timer, ADC, PWM, and comparator which are built in the MCU, the necessary parameters will be measured without extra components and additional cost. The proposed method is based on those parameters. In this paper, the MATLAB/Simulink simulation results show the proposed method workable.

Simulation Results

Mobile equipment such as organic-EL display, digital still camera and so on re-quire both positive and negative power supply voltage to obtain high quality. Single InductorMultiple-Output (SIMO) DC-DC converter can provide a pair of positive and negative outputvoltages with only one external inductor. This paper describes SIMO DC-DC Converter usingproposed current-mode control (CMC) circuit. The proposed CMC circuit realizes high responsespeed for the change of load current. Spectre simulations with 0.18m CMOS process parameterare performed to verify the validity of the proposed converter. The simulation results indicatethat the proposed converter has higher response time compared with conventional converter.

A switched mode power supply (SMPS) with multiple outputs has been developed which satisfies the need of isolation of control circuit power supply and driver section power supply for a medium-voltage electrical drive. It means that there is no need of extra components for isolation. For this SMPS, fly-back converter topology along with current mode control method is selected and its performance is observed for line, load as well as cross regulation with other tests. This SMPS generates multiple outputs of +5 V, +24 V, +/- 15 V and five +24 V isolated output voltages.

The integration of digitization and soft-switch technology can improve the power control accuracy and reduce the volume of power, etc. The response of traditional DC/DC converter's control method was slow and the implementation of digitization was more complex. Therefore, this paper presents a zero-voltage zero-current (ZVZCS) full-bridge DC / DC converter digital control system which adopt parallel current-mode control method and advanced circuit topology combining with ARM processor. Finally, the results of simulation and experimental verify Simulation and the zero-voltage zero-current converter topology is reasonable, parameter design is correct, consistent with the expected theoretical analysis, digital control strategy is feasible.
