Definitions

  • the invention relates to a power management system and methods to provide low voltage
  • the traditional early means for providing DC power from an AC mains was through analog circuitry that included a step-down transformer, a diode rectifier, and a filter comprising an electrolytic capacitor and resistor.
  • the output voltage depended primarily on the turns ratio of the transformer and the circuit was moderately efficient.
  • the size and weight of the magnetic structure required to implement the low frequency transformer obviates the use of this approach in miniature equipment.
  • a later approach that does not use a transformer involves the direct rectification of the AC mains which is directly connected to a voltage regulation circuit comprising an active solid-state device in either a series or shunt connection.
  • the shunt regulator works by providing a current path across the rectified mains output through a variable resistance device, thereby diverting current away from the load.
  • a Zener diode is connected in shunt with the load with a resistor in series with this shunt leg. Any rectifier output voltage in excess of the Zener voltage is dropped across the resistor resulting in the excess power being dissipated as heat.
  • this regulator configuration is very inefficient. Since the Zener current must be larger than the load current to maintain regulation through the Zener effect, the efficiency of this regulator circuit is much smaller than the ratio of the output voltage to the rms value of the rectified supply voltage.
  • An improved approach uses a series connected solid-state device, such as a bipolar or field-effect transistor, to buffer the Zener voltage reference.
  • the active device is connected in a source-follower or emitter-follower configuration, with the load connected at the source or emitter and the Zener reference connected at the gate or base.
  • the Zener current can be much smaller than in the shunt configuration, so the total current is largely that supplied to the load. Thus, the efficiency of this circuit is generally no better than the ratio of the input to output voltage.
  • a further improvement to this circuit function is termed a switch mode power supply.
  • a switch mode power supply There are numerous such designs known in the art, but the commonality is an input rectifier, a switching element that operates at high speeds to switch a storage element, inductor or capacitor, into and out of the supply. If isolation of the input and output is required a high speed transformer is included for isolation and to regulate the output voltage. RC filters are included to reduce ripple in the output. Switch mode power supplies have an advantage of increased efficiency since the power loss mechanisms of the early linear systems are largely eliminated. However, there are transformer losses if isolation is required. Also, the high speed switching is a source of considerable RF noise as well as losses in conductors due to skin effects. Theoretically high efficiencies can and have been obtained in specially designed systems.
  • the power supply must be able to be integrated into the sensor and control electronics to enable such devices to physically fit within the confines of plugs and outlets used to supply local power.
  • the system includes an efficient electronic switch employed to disconnect the input of a series voltage regulator circuit from a rectified AC mains power supply to reduce the power dissipated within the series regulator. While the switch is closed, energy is accumulated and stored in a shunt energy storage element. The electronic switch is opened when the rectified AC mains waveform exceeds a threshold value. While the switch is open, energy is supplied to the load by the energy storage element through the regulator circuit.
  • a comparator is used to control the electronic switch.
  • the comparator is comprised of an operational amplifier and a reference voltage source.
  • the comparator is comprised of a MOS field effect transistor.
  • the MOS field effect transistor is controlled through a voltage divider.
  • the voltage divider is replaced with a reference voltage source.
  • the reference voltage is adjustable.
  • Figure 1 is a schematic diagram of a prior art AC-DC converter.
  • Figure 2 is a schematic diagram of a prior art AC-DC converter with current limiting.
  • Figure 3 is a schematic diagram showing the functions in the improved circuit.
  • Figure 4 is a schematic diagram showing the improved AC -DC converter.
  • Figure 5 is a schematic diagram of an embodiment of the improved circuit using MOS field-effect transistors.
  • Figure 6 is a schematic diagram of the embodiment of Figure 5 including a current limiting function.
  • Figure 7 is a schematic diagram of an embodiment of the improved AC -DC converter using MOS transistors.
  • Figure 8 is a schematic diagram of an embodiment of the improved circuit using MOS field-effect transistors in which the output voltage is manually adjustable.
  • Figure 9 is a schematic diagram of an embodiment of the improved circuit using MOS field-effect transistors in which the output voltage is electronically adjustable.
  • Figure 10 is a schematic diagram of an embodiment that eliminates the need for a rectifier.
  • Figure 11 is a schematic diagram of an embodiment that modifies the embodiment of Figure 10.
  • FIG. 1 shows a schematic diagram of a prior art AC -DC converter circuit.
  • AC mains 101 are full-wave rectified by diode bridge 102 and the resulting time-varying DC voltage waveform is smoothed by capacitor 103.
  • the smoothed voltage waveform is applied to the input of a series regulator circuit including bias resistor 104, Zener diode 105 having a characteristic Zener voltage Vz, and pass transistor 106, here represented as an enhancement mode MOS field-effect transistor (MOSFET) having a characteristic threshold voltage, Vj.
  • MOSFET enhancement mode MOS field-effect transistor
  • the pass transistor 106 dynamically adjusts its drain-source voltage to keep the load voltage at Vz-Vj.
  • pass transistor 106 forms a source-follower circuit that buffers the Zener voltage, Vz. Since the full load current passes through pass transistor 106, the efficiency of this regulator circuit is simply the ratio of the load voltage to the rms value of the supply voltage. Thus, if the desired load voltage is nominally 3.3V and the supply voltage is 120V rms, then the efficiency is less than 3%.
  • pass transistor 106 must continuously dissipate several watts of power as heat. This amount of dissipation typically leads to an unacceptable temperature rise in miniature, enclosed equipment.
  • FIG. 1 shows a schematic diagram of a prior art AC -DC converter that includes additional components to limit the output current, thereby protecting the pass transistor.
  • a small current sensing resistor 201 is placed in series with the load, and bipolar transistor 202 is connected between the gate of the pass transistor 106 and the load.
  • FIG. 3 shows a schematic diagram of an improved rectifier circuit that includes the AC mains 101 , the diode bridge 102 and filter capacitor 103, but having additional circuitry inserted between the diode bridge 102 output and the filter capacitor 103.
  • the waveform at the diode bridge 102 output is simply a full-wave rectified sinusoidal waveform that conventionally varies from 0V to approximately 170V peak for a conventional AC mains having an rms value of 120V. Note, however, that the method described below applies to any periodic power waveform assuming that the numeric specifications of the affected components are suitably adjusted. Additionally, the power waveform can include a DC offset if it is smaller than the reference voltage described below.
  • the additional circuitry includes a comparator circuit 302 having its inverting input connected to the diode bridge 102 output and a voltage reference 301 connected to its non-inverting input, wherein the comparator 302 controls a series switch 303 that disconnects the diode bridge output from succeeding circuitry (opens switch 303) if the diode bridge output voltage exceeds the reference voltage V R .
  • switch 303 is closed and capacitor 103 is charged through series diode 304.
  • Diode 304 keeps capacitor 103 from discharging back through switch 303 when the diode bridge output voltage decreases.
  • the combination of diode 304 and capacitor 103 form a "peak detector" circuit that stores energy in each one-half of an AC mains cycle to supply to subsequent regulator circuitry and the load 305.
  • the voltage across capacitor 103 need only be large enough to satisfy the energy requirement of the subsequent regulator circuitry and load 305.
  • the input voltage to the series regulator is significantly reduced compared to the rms value of the AC mains.
  • the operation of the "peak detector” circuit ensures the steady-state voltage stored on capacitor 103 is always V R , regardless of fluctuations in the peak voltage of the AC mains, as long as the voltage of the AC mains remains larger than V R .
  • This embodiment of a switching circuit operates as a voltage regulator circuit itself.
  • switch 303 Since the operation of switch 303 uses negligible energy, the efficiency of the overall improved AC -DC converter circuit shown in Figure 3 is much larger than seen for the prior art circuits of Figures 1 and 2. An additional benefit is a significant reduction in operating temperature rise.
  • the comparator 302 is a well-known analog circuit element other analog or digital circuits could be employed to accomplish the desired thresholding function needed to operate switch 303.
  • the reference voltage VR is fixed. In another embodiment, the reference voltage can be varied. In another embodiment the reference voltage is selectable. In one embodiment the circuit of Figure 3 is connected to the load and the regulator aspect of the circuit is used to control voltage supplied to the load. In another embodiment an additional regulator is used in series with the circuit of Figure 3 and the load.
  • FIG 4 shows a schematic diagram of the improved rectifier circuit interconnected to the series regulator 103 - 106 from Figure 1 and provides a convenient basis for establishing the relationships among design variables in the new rectifier circuit.
  • Vz Zener voltage
  • capacitor 103 will discharge linearly in time over a half period of the AC mains due to the current provided to the load 107.
  • V peak result in higher power dissipation in pass transistor 106, and this can be traded against the maximum practical value of capacitor 103.
  • the efficiency of the regulator is the ratio of the power delivered to the load divided by the total power dissipated in the circuit and is given by 2*(Vz-VT)/(Vz+Vp eak ).
  • FIG. 5 shows a schematic diagram of the improved rectifier circuit wherein the switch 303 is implemented using an enhancement mode MOSFET 505 and the comparator circuit is realized as a single common-source amplifier stage also using an enhancement mode MOSFET 504 characterized by a threshold voltage, V T , and a load resistor 503.
  • V T threshold voltage
  • MOSFET 505 is not an ideal switch, and significant power dissipation may be experienced while it is in its conducting state, so that the efficiency of the circuit realized using MOSFETs will not be as great as that obtained in the ideal case shown in Figure 4.
  • power MOSFETs typically include a parasitic source-to-drain diode 506 that can allow capacitor 103 to discharge when MOSFET 505 is "off.”
  • Series diode 304 obviates this spurious discharge path.
  • the existence of the parasitic diode 506 is assumed in subsequent diagrams. Note that it is feasible that, with the possible exception of energy storage capacitor 103, all of the components of Figure 5 could be fabricated on a single semiconductor chip.
  • Figure 6 shows a further improved rectifier circuit now including bipolar transistor 601 and current sensing resistor 602 to limit the charging current through MOSFET 505 and diode 304 as previously illustrated in Figure 2 as an improvement to the prior art series regulator circuit shown in Figure 1.
  • Figure 7 is a schematic diagram showing the complete high efficiency AC -DC converter with the improved rectifier circuit of Figure 6 connected to the series regulator 103 - 106 shown in Figure 1 .
  • Figure 8 is a schematic diagram of an embodiment of the improved circuit using
  • Figure 9 is a schematic diagram of an embodiment of the improved circuit using
  • MOSFETs in which the output voltage is electronically adjustable. Additional MOSFET 901 is connected in place of resistor 502 in Figure 5 and an external DC control voltage, Vc, is applied to the gate of MOSFET 901, thereby changing the voltage applied to the gate of MOSFET 504 and changing the voltage stored on capacitor 103.
  • Vc DC control voltage
  • the full-wave bridge rectifier 102 is eliminated and the AC mains 101 is connected directly to the voltage divider 501, 502.
  • the embodiment shown in Figure 6 is used without the rectifier 102.
  • Analogously other embodiments include the embodiments described in Figures 7 - 9 except that the rectifier 102 is removed.
  • Figure 11 is a modification of the embodiment shown in Figure 10 that includes rectifier diode 1101 which acts as a half-wave rectifier and relieves such stringent electrical requirements imposed on switch 505 by the circuit of Figure 10.
  • the system consists of an efficient electronic switch employed to disconnect the input of a prior art series voltage regulator circuit from a rectified AC mains power supply to reduce the power dissipated within the series regulator. While the switch is open the regulator provides power to the load from an energy storage element. In this way the benefits of the regulator circuit accrue to the attached load circuitry while the power dissipated within the regulator circuit is greatly reduced compared to the prior art.
