Introduction Nowaday, liquid crytal diplay (LCD) panel are widely ued in application uch a monitor, notebook and televiion [1]-[2]. In large cale LCD TV (>30 ), the power upply typically require an output power range from 200 W to 600 W. A the creen area increae, the power required for the 24-Vdc rail continue to rie until it i no longer practical to implement the SMPS uing a flyback topology. A a reult, a variety of higher-power topologie, including the half bridge LLC topology, ha been conidered to achieve high efficiency in a compact pace with low-emi generation [3]-[4]. In thi paper, the deign of a digitally-controlled LLC reonant converter i preented. The LLC reonant topology allow for ZVS of the main witche, thereby dramatically lowering witching loe and booting efficiency. A digital ignal controller (dpic30f2020) from Microchip corp. i utilized a the digital controller of the LLC reonant converter. Digital power alo provide intelligent adaptability and flexibility to atify any complex power requirement with the traightforward ability to monitor, proce and adapt to ytem condition [5]. In order to deign the compenation circuit correctly, the large-ignal and mall-ignal model of the utilized LLC converter i alo derived in thi paper uing the phaor tranformation method [6]-[7]. Finally, experimental reult are preented to validate the correctne of the propoed ytem. The meaured efficiency of the whole ytem achieved 87 %. 2. Hardware Decription Fig. 1 how the circuit configuration of the propoed digitalized LLC reonant converter. From Fig. 1, the whole hardware ytem can be divided into two major part: LLC reonant converter DC/DC power tage and digital controller. Detailed decription about each part will be given in the following ubection LLC reonant converter The half-bridge LLC reonant topology i utilized in thi paper to convert the output voltage of power factor corrector front tage (typically 400 V) into voltage needed to upply the functional block uch a backlighting, microproceor and interfacing circuit, etc. LLC reonant converter i widely ued in conumer application uch a LCD TV or plama diplay panel with output power level range from 200 W up to 600 W. The advantage of LLC converter include: ZVS capability over the entire load range 55
2 Lower electromagnetic interference (EMI) Zero current turnoff of the econdary diode No increaed component count comparing to conventional half bridge topology. From Fig. 1, the primary ide of the LLC converter i a half-bridge configuration. The econdary ide i a center-tapped rectifier followed by a capacitive filter. Switche S 1 and S 2 are both driven by 50 % duty cycle gating ignal, with a mall amount of dead time introduced between the conecutive tranition. The circuit ha three paive component, L r, C r and L m, where L m i the magnetizing inductance that act a a hunt inductor, L r i the erie reonant inductor, and C r i the reonant capacitor. Fig. 2 how the typical waveform of the preented LLC reonant converter. From Fig. 2, the operation of half of witching cycle can be divided into four mode. (1) Mode 1 (t 0 < t < t 1 ):at t=t 0, S 1 turned on. During thi mode, output rectifier diode D 1 conduct. The tranformer voltage i clamped at V o. L m i linearly charged with output voltage, o it doen t participate reonant during thi period and V p = n V out. The current i Lr and i Lm increae. The energy flow through the reonant tank and tranformer and to the load. Thi mode end when i Lr current i the ame a i Lm current. Output current reach zero. (2) Mode 2 (t 1 < t < t 2 ):at t=t 1,, the two inductor current i Lr and i Lm are equal. Output current reache zero. Both output rectifier diode D 1 and D 2 i revere biaed. Tranformer econdary voltage i lower than output voltage. Output i eparated from tranformer. During thi period, ince output i eparated from primary, L m i freed to participate reonant. Thi mode end when S 1 i turned off. (3) Mode 3 (t 2 < t < t 3 ):at t=t 2, S 1 i turned off. During thi mode, S 1 and S 2 are both off. The reonant current i Lr charge (dicharge) the paraitic capacitance C o1 ( C o2 ) of the power witche. When the voltage acro C o1 equal V in, the body diode of S 2 i turned on. (4) Mode 4 (t 3 < t < t 4 ):The body diode of S 2 i turned on in previou mode, which create a ZVS condition for S 2. Gate ignal of S 2 hould be applied during thi mode. When S 2 i turned on, i Lr decreae and thi will force econdary diode D 2 conduct and i out begin to increae. Alo, from thi moment, tranformer ee output voltage on the econdary ide. L m i clamped with contant voltage Vp = n Vout, o it doen t participate reonant during thi period. For next half cycle, the operation i ame a analyzed above and i omitted here Digital controller In thi paper, the dpic30f2020 digital ignal controller (DSC) from Microchip corp. i ued to control the preented LLC reonant converter. The propoed digital power upply offer a new freedom for uer to control the power output of the LCD power upply according to the power requirement, thi lead to an energy economy. When compared to an analog one, digital control boat everal advantage uch a the poibility for implementing ophiticated control law allow the deigner to modify the control trategy without ignificant hardware modification higher tolerance to ignal noie and the complete abence of ageing effect or thermal drift the poibility to provide man to machine interface (MMI) The digital controller utilized in thi paper i a conventional PID controller; the digital control algorithm can be deigned a: un ( ) = un ( 1) + K0 en ( ) + K1 en ( 1) + K2 en ( 2) (1) where E(n) i the error ignal and U(n) i the input ignal. It hould be noted that the LLC converter work with variable frequency control. Thi implie that power flow can be controlled by changing the operating frequency of the converter in uch a way that a reduced power demand from the load produce a frequency rie, while an increaed power demand caue a frequency reduction. Unlike the conventional PWM control trategie in which the duty cycle i the control variable. For LLC converter, the control variable i the witching frequency. Therefore, for the preented digital controller, the output of PID controller hould be fed into the Period regiter of the utilized PWM 56
3 module while the PDC (duty cycle) regiter hould be et a half the value of that in Period regiter to obtain 50 % duty cycle. Fig. 1 Circuit configuration of the digitalized LLC reonant converter Fig. 2 Typical waveform of LLC Reonant Converter 3. Small-ignal Model of the LLC Reonant Converter In order to deign the parameter (K p, K i and K d ) of the compenation circuit, a mall-ignal model hould firt be obtained. In thi paper, the phaor tranformation method a preented in [6] i utilized. In [6], a modified phaor tranform a hown in Eq. (2) can be ued to apply to variable frequency operation. j () tdt xt () = Re[ xte () ] (2) where x() t i the time-varying phaor correponding to x(t), which preent the amplitude of x(t), and () t i time-varying intantaneou frequency. Uing Eq. (2), the phaor equation for reitor, inductor and capacitor can be derived repectively. Uing the ame technique, the phaor preentation of a general witching network and a rectifier with a tranformer can alo be obtained. Since the LLC reonant converter only conit the above-mentioned part, the large ignal and mall ignal model of the LLC reonant converter can be obtained and are preented in Fig. 3. Uing thi mall-ignal model, the tranfer function can be derived and the compenation circuit can be deigned accordingly. Fig. 4 how the open loop and cloe loop bode plot of the preented ytem. From the cloe loop bode plot, the cut-off frequency i 20 khz and the phae-margin i 55.8 degree. The obtained compenation circuit parameter can be decribed a G () = G c c0 z (1 + ) z2 (1 + )(1 + ) p K I = KP + + KD (3) 57
